288xp not running correctly

[husky01]

I bought a 288 and it had very low compression so i bought a good 2nd hand cylinder and piston for it. the compression went like it was a brand new saw, the first 10 minutes of running time it was good then it dropped to almost zero compression. i have checked all the obvious reasons, cylinder bolts, spark plug ect.

I still don't no what is wrong with it so any suggestions would be appreciated.

Stuck ring pull the muffler have a look. You fixed the symptom but not the cause. Just my guess.

Pull the muffler off and check your piston,....for scoring.

You better find the cause for the scoring before putting another P&C on that saw again.Most likely it has an air leak, a vac test is in order.

Vac and pressure test before you run that saw next time. Like Lone Wolf said, there's a reason it died the first time....Hopefully your cylinder cleans up again, ok.:msp_thumbup:
