4 Stroke engine clutch problems!!

[xXNightRiderXx]

If you bang one out, absolutely DO make sure that both the bell and the shaft turn straight, and aren't dented when it's done. Dents in the bell will cause low spots that can grab the clutch at idle. Dents in the shaft will just make it harder to put the sprockets on. I'd say try using your old bell as a practice piece so you can get your new one banged out proper.

If you buy one, same thing. Make sure it turns straight, and has no dents.

I'm glad you got it fixed! How does it climb now?

Now another problem has arisen, no longer banging it, but later it engages the clutch literally before it completes the course of the massage, and it has to be driven at maximum speeds so that I can set the clutch to open the springs slightly, or is there no chance?

You may have gotten a high stall clutch then. All you gotta do is get lighter springs for it.

They're for sale right?

I'm not 100% sure on that one, but clutches are cheap in case you can't find any. You may want to browse a while before settling on a choice. I did a lot of research before settling on and changing to heavier valve springs.

I solved this problem and just stretched the springs slightly and got the problem clear. The springs can be adjusted. I also noticed that these engines are quite prone to clogging the carburetor. yes any but these engines don't eat everything !!

Nice ingenuity. Get paper fuel and air filters installed. That will reduce the clogging if not stop it. The foam elements might as well do nothing to filter out all the road dust and crap.
