372 won't rev past idle
« on: May 25, 2018, 09:13:32 pm »
I have a 372 that won't rev past idle- just a stubborn put-put-put.... Finally stalls.
This saw was a 365 that I put a 372 head and piston on last year and it ran great.
I ordered and just installed a new carb complete, ignition module, plug.
Same issue . The air filter is off, muffler off- no better. Piston looks fine through the ports... I'm stumped
