  1. Will the Honda last more than 3x as long as the knock offs?

  2. Water does a better job. Spray it through the carb while engine is working hard.

  3. Why go outside (in the rain) for a brick when the available jack does the job.

  4. I had the green version of Slime (for tubed tyres) cause problems on alloy rims. The Slime latched onto bare metal (scratched by tyre levers) causing a lumpy clag that affected wheel balance. I would not use that grade in tubes or in tubeless as it does affect the metal. PunctureSafe/WellSeal is a tubeless grade. It did exactly what it says on the tin and saved me many times with punctured motorbike rear tyres.

  5. I used Slick 50 in a 1990 diesel. The turbo failed at 140K miles. Pretty standard for that engine.

  6. I had a puncture caused by an M6 (1/4") bolt easily sealed by Wellseal/Puncturesafe. But it absolutely would not have sealed a hole drilled to 1/4" diameter.

  7. Lumiweld Aluminium solder rods have been about for donkey's years. back in the 1980s a workmate used it to repair a VW Beetle gearbox0engine mount lug. We all said that can't work. But it really did and he ran the car for years. The snag is that it's not welding, you can't do one side and flip it over. because the stuff melts and runs out. A thick part has to be dammed up with high temperature putty so it can be solder filled from one side. Then fettle it clean and drill out any holes.

  8. The engine test would probably be much the same with any grease. It can’t get into the bearings.

  9. I replaced the flexible oil pipes on a motorcycle with fluoro lined silicone. The recommended worm clips were actually too big. They went D shaped before the connection sealed. The next size down opened almost to separation sealed perfectly when tightened down.

  10.  @daviddefortier5970  "Engine restore" was almost certainly just as ineffective.

  11. My corded Makita (£55) lasted about 2 years of DIY use before the spindle lock fell apart and shattered the gearbox. The Parkside replacement (£30) has been going strong for years with a similar rate of use. I bought another when they had them in stock along with a battery version. That needs a 4AH battery. The 2AH trips on overload.

  12. Propane is usually gassified before going into the engine. We can now get liquid phase injection systems. They need injectors fitting to the inlet manifold but run with no performance loss and almost identical miles per gallon.

  13.  @BL-yj2wp  Every gallon of petrol (gasoline) burns to a gallon of water plus CO2. If the car is used for short journeys (never getting fully hot), some of that water gets into the crankcase and will contaminate the oil. A blown cylinder head gasket can allow coolant into the engine oil, but the engine would soon be overheating and obviously not well. Continuing to drive like that would kill the engine. Oil contamination would be the least of your worries.

  14.  @wvadam  The two-strokes sold for bike frames are little better than stuff made in the 1950s. However a modern clean 2 stroke is not cheap but it would be cheaper than an equivalent power 4 stroke that's equally clean. Check out the Rotax ETEC used in Skidoos and Evinrudes. Very clean, excellent lugging power, good fuel consumption and makes 160bhp from 850cc. It beats the competing (very heavy) 1200cc 4 strokes on all levels including power and fuel consumption and easily meets the stringent USA EPA requirements. 2 strokes lubed by oil mixed in the fuel always suffer compromise. Full throttle = not enough oil without smoke. Closed throttle = no oil at all. They also stutter and missfire on part throttle causing pollution and the piston etc gets hammered about. Today's DI engines solve both problems and they don't produce a gallon of toxic sump oil every few thousand miles that (some) people pour into a hole in the ground.

  15. The 1950 oil would be used in low compression side valve engines (like the mower). It's surprising to see so much blow-by. Those old engines used a gravity dirt trap. There was no inline paper element filter. They need a basic oil that does not keep dirt in suspension. Modern oils should not be used because there is no paper filter to catch the suspended dirt. These oils are actually worse for old engines than old spec oils..

  16. The old high sulphur diesel was quite lubricating. Modern low sulphur is not as good. It would need castor oil adding.

  17. Kia and Hyundai cars are as good as any other. And they are not MBWVBenz

  18. The folding stands will degrade over time (rust west n tear etc). Those with a ratchet centre support should last a lifetime if not abused.

  20. Fluorescents throw the light all around. 50% is wasted especially on a dark ceiling. LEDs throw light directly where it’s needed. They don’t even need the old light fitting.

  21. LiFePo4 won’t work well below 5 degrees C. It’s no problem just don’t leave it in the car overnight. The big advantage is the low self drain(10% per year). I had a 4 Amp Hour JMT that started a 1200cc bike just as well as a 14 AH AGM lead acid. In cold weather you apply a load to warm the battery. It then delivers full current.

  22. Check out the cable sizes at https://www.wiringproducts.com/battery-cable. The jumper cables with these batteries are very much on the side of not big enough.

  23. Action Can CS-90 is a mix of copper and graphite. It works fine on stainless bolts into aluminium (about as bad as it gets) where the hole is open at the back. I’ve had the stainless bolts shear off after just one U.K. winter. They were always just fine after using the paste - no Al oxide whatsoever. I don’t know the chemistry but Aluminium sits at 4 on the galvanic scale. 30x stainless is at 30. copper sits at 13. I would like to better understand the chemistry but believe it works by interrupting the battery effect. Stainless to Al = 1.6 volts Stainless to copper = 0.35 volts.

  24. Wikipedia says - Coleman fuel has an octane rating of 50 to 55 and a flammability similar to gasoline, it has none of the additives found in modern gasoline. Most burners will readily burn unleaded gasoline (or white gas). It's likely to knock pretty badly in anything but a lawn mower.

  25. Putting hinges onto a green oak gate post caught me out. It moved as it does so had to reposition a hinge. The exterior grade galvanised screws all sheared off. I used wall plugs on the replacements. No corrosion and removable years later.

  26. I would not buy the knock-off exactly because it’s a knock-off. If they had changed the colour and called it Eddie then maybe.

  27. Koziba Warona Chaboneka worm computer fans whirl and rattle. Lubes will help but it’s a sign the bearing is on the way out.

  28. The best way to wash used cooking oil is to boil it over water. The rising steam strips the dirt. Biodiesel needs dry oil so tap the clean oil from above the water. Drain the dirty water and remove debris for composting. Similar system will wash the biodiesel but first it must be separated from the dark glycerol soap. You don’t want that in the engine. Vegetable oil burns nicely in diesel engines but must be heated to 80 degs C. About 180 degs F to avoid stock carbon deposits. Glycerol chars before it burns but preheating the oil allows a clean combustion.

  29. Two stroke oil stops pistons seizing at ratios 1/50 with gasoline. That's mixed with air at 1/12 to 1/14 so the amount of oil inside a "stroker" engine is very low.

  30. The Yobbo brand batteries all make the same claims almost to the letter. Probably from the exact same factory.

  31. When I was a kid we ran a 50cc moped on kerosine. It had to be started on gasoline but when switched to kero it would continue to run and made usable power. Kerosine and diesel are similar but they stink in a low compression engine.

  32. During the (bad?) days of lean burning engines the exhaust tip would be pale grey and cylinder heads were clean. Catalysts need fuel to operate so engines are run slightly rich. Regardless of fuel injection, that leads to carbon in the head and exhaust above the catalyst.

  33. are they both the same cc?

  34. The best rounded nut remover is a good nut welded on top. The sharp heat input shocks the seized threads and the new nut gets some purchase on it. My bike had the most ridiculous socked ended nuts on the exhaust manifold. Yes really. They were perfect for letting salt into the threads and rusted solid. A bead of arc weld on each one got them off with no broken studs.

  35. I can see the carbon settling out into the sump and elsewhere but cannot see why it would affect the catalytic converter. Poor fuel burn also produces carbon which does not damage the cat.

  36. Brake fluid absolutely ruins paint. If left on bare metal it’s water absorption eventually makes it corrosive. It can be cleaned off bare metal but if the paint has been eaten away there will be rust.

  37. Low compression engines with fixed timing will perform no better on fancy gasoline than cheap gas. Fuel injected with knock sensors allows the spark to advance to the ideal point. That puts less heat down the exhaust and more into the road.

  38. Knippex cut beautifully but the sharp blades make them useless for pulling nails.

  39. Excellent work. I use the plain self drilling/threading type in metal. The plastic versions often get damaged by plaster skim. They don’t cause too much damage. They can’t carry the ultimate weight so just use more than one or find a frame timber.

  40. Two stroke gas with a thick mix can make the 4 stroke run weak (the oil doesn't burn like gasoline), but in every other respect its still at least 96% gasoline.

  41. Check out David Vizard’s findings with K& N filters. He found the amount of dirt trapped meant far less engine wear (and therefore power fall/off) than was lost by air restrictions through the filter. He went on to prove it on the track with NASCAR engines.

  42. Its the stop start BS that shoves up the costs. Why are we not using LiFePO4 batteries. Similar costs but a much longer working life (2000 full charge/discharge cycles). They do need an internal heater for cold starts but their capacity is more than up to delivering that additional power. The huge cranking amps figures are pointless. A 2 litre starter will max around 400 amps on a stone cold engine. https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&cad=rja&uact=8&ved=2ahUKEwi58YTzopvqAhUJecAKHVljBw8QFjABegQIDBAE&url=https%3A%2F%2Fwww.electro-tech-online.com%2Fthreads%2Fstarter-motor-amps.36783%2F&usg=AOvVaw0Lk7jGR0I4TG1ZWzVx_AJn

  43. Sometimes it’s better to hang the lights at 8ft from the floor. You might also find the high intensity over the bench is all you need. Other areas can be lit with less power.

  44. It’s alleged to offer less engine wear. But as even the posh stuff with Teflon had no measurable effect it’s unlikely to do anything.

  45. I always used Wellseal/PunctureSafe on motorbike rear tyres. It MUST be the tubeless version and DO NOT use too much. It worked fine with tyre pressure sensors. Though I did pump up the tyre with valve core removed to fully blow it out before fitting the core. No tyre damage and no metal corrosion. However inner tube sealants can cause corrosion. I would never use them - any leaks = ??? https://www.amazon.co.uk/Puncturesafe-Puncture-Safe/dp/B001KTYQT6/ref=asc_df_B001KTYQT6/?tag=googshopuk-21&linkCode=df0&hvadid=310632529194&hvpos=&hvnetw=g&hvrand=6137164513068070432&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9045321&hvtargid=pla-585444640734&psc=1

  46. Jet fuel burns slower than gasoline so more heat goes down exhaust. Low compression engines will work on low spec fuels. High compression more efficient but needs a fuel that won’t pre-ignite. Ping/knock.

  47. I had a faulty injector on a VW 1.9 TDI. 100,000 miles before it happened. Diesel overfilled the sump enough to leak oil. I assumed there would be engine damage but fitted a new injector and new oil. It ran for another 30,000 miles with no problems.

  48. I use centre bits for accuracy then follow with a step drill. Over all it’s quicker than waiting for the step to struggle through the first cut. Sometimes it’s just easier to use a normal drill for starting with the step for bigger holes.

  49. The welder method can work but extremely flat cells often go reverse polarity. Been there done that. Optimate does work and won’t reverse polarity any cells.

  50. How much air does a generator engine pull per second? That daft little HHO bottle will be sucked empty in the first turn of the engine.
