      On a kohler 18hp twin that's on a craftsman rider if the plug is oil wet than I can assume the rings are bad and engine needs to be rebuilt? Do I need to buy a compression tester?

      said no one ever 😂😂.
      There are way more variables to take into account in tuning big engines, specially carbureted engine.
      No saying small engine mechanics are dumber, just not in the same level. Anyone who has touched a wrench in his life will know.
      It’s like comparing a house electrician with an electrical engineer in charge of the city’s electric distribution systems. 😂😂

      Dude I have been saying this too people lately and people just kinda looked at me crazy. My arguing point is this I can make a ford,dodge,Chevy run no problem. Now when you start trying to fix a small engine and make it run good/excellent I personally have to go back and do my research. Even then they give me hell

    Quite true, several years ago i changed spark plugs on an i6 and noticed oil on two of them. The engine ran, but definitely less ideal.
    I think it's simply because the spark plugs are the only thing easy accessible in the combustion chamber.

    I ordered a Husqvarna 128ld. Whenever I got done breaking it in I noticed that it sounded very rich in the low speed needle so being the mechanic I am, I leaned it out and made sure it sounded a bit rich in the high speed needle and it did so I started to use it. Whenever I was done I let her cool off and then I took the plug out to see what type of mixture it was running at. and to my surprise 1/4 of the porcelain was black and the rest was still white. So I tried to richen the high speed a bit more and after holding the throttle fully for about a minute I took the plug out again but it was the same color and instead of it being dry carbon around the threads, it was a bit wet. Does it take more than 30 minutes for the color of the porcelain to change? And also does anyone know the oem specs of the needles?

    I bought a bike that has been sitting for 10 years and when I got it the oil was all black as well as the spark plug all black and full of soot. What do I need to do before replacing the spark plug with a new one? Should I clean the inside where it sits or spray it with something first? I've changed the oil and gas and cleaned the carb. The bike ran very bad before and died when reaching 4:th gear after some time and when riding it for a while. So I have it taken apart now since I will be replacing the petcock since it was leaking.

I have clean the carburetor got a new spark plug check the magneto gap and a new fuel filter and cleaned the air filter and the primer bulb is new. It’s hard to start cold but it will fire up on full choke and then as it warms up it dies off and won’t start back up from there I end up flooding the motor just trying to start it.

      Modern automobile engines tend to run what looks like "lean" according to old plug examination standards, so that's actually normal. The one covered in oil isn't good. You probably have bad rings or sludged up oil control rings or drain back holes on that piston.

      @smiling.buddha ปีที่แล้ว +1

      It means that in the air fuel mixture, there is more fuel than needed that results in black soot. This may be due to bigger jets or low float height in the carburettor. Other possibility is, it can also be correct amount of fuel but less air due to clogged air filter which again results in to black soot.
