Newbie looking for help with Honda GX240 that won't run

If the problem is truly here, then buffing out the valve stem/shank, a new head gasket, and spark plug thread repair should get you back on track.

I never bothered about the dripping carb in the videos, but you would need to figure that out too.

Also, you will need to ensure that the flywheel nut is tightened/torqued back on properly. If you have an impact wrench, just fap it back on with a sensible amount of impact action. Hard to convey this quantity over a distance.....

I just looked at your post #98 could you tell us if the center of the piston has a pin hole in it from the pic it looks like it could have one but I cant tell from the pic to be sure. the center of the piston has erroison and at the bottom theres a lite tan or white dot about the size of a pin

No, there is no hole - I think that may be a camera artifact or a reflection - I don't see it when I look at the piston.

Is is sticking because of some interference on the valve shank where it meets the guide. Any burrs or ridges?

I think it may be a false alarm. I didn't notice there is a a rubbery cap on the guide for the intake valve. That is what was grabbing the valve stem. I took it off and now the valve moves freely.

It was a seal. I am assuming.

Ok now we know that the intake valve is tight and sticking now it comes down to what you would like to do fix what you have or buy a new engine from HF.

The dripping carb is a bowl gasket issue that happened after I cleaned the carb. I didn't have a carb rebuild kit or carb gaskets.

I'm not going to try to fix it at this point. If I'm not 99% sure I know what the problem is, I don't want to spend any more money on it. Since I don't work on these engines regularly, I don't have any other use for any parts I buy or fix. If I fix the spark plug threads and can't fix the whole engine, I'll just have a head that I'll never use. I've just been following up here because I was asked to to satisfy all our curiosities on what the problem really was.
