Too much?

[Craigb]

346xp ne. Gasket delete and a new muffler I welded a 20mm dia pipe into at work. Is the pipe too big? It also has 200psi of compression now. Runs and cuts great. But I’ve done what only other men can dream of, the impossible, the chain creeps ever so slowly in the wrong direction at idle, corrects when revved though. What’s your thoughts?

That's way too much, send it to me for safe disposal. Forwards chain creep means overly loose clutch springs therefore backwards chain creep logically means overly tight clutch springs 🧠

 

No but really I'd measure your squish and confirm it's not too low. One of my 254's ran and cut great with 0.017" squish, which might even be OK on a 50cc saw, but I wasn't comfortable. Would rather have long lifespan than very high compression personally.
