Re: John Deere 332 Compression
Tracs, If you're getting those numbers on a cold engine and the manual specs 355, I'd say it's not an engine problem...or at least not a compression problem.
AFTER engine runs for 5 minutes or so, go 1/3-1/2 throttle, engage pto and go full throttle. Listen to engine as you start moving snow. If engine starts to bog, reduce ground speed. Even at WOT, the second stage can only blow so much snow. Sounds to me like your moving too fast, the second stage gets loaded up and then the auger...stalling the engine.
I have a 14 hp with a 49 (single stage) thrower and found too fast a ground speed would clog thrower or stall engine. WOT and ground speed are the key! Bob
