Hi all,

One issue I ran into with a 35cc homelite chainsaw convert was had very bad vibes when using a heavy prop (master airscrew). A switch to a wood prop really smartened it up. Both props were balanced- the MA was rechecked and too this day this engine only likes light wood not heavy glass.

The engine was solidly mounted as I gave up trying to get softmounts to work (with the MA). When the wood blade was bolted on the vibe issue went away. When any heavy glass blade was tried the vibes came back.

Has anybody else seen this happen? Anybody with a theory? I have not experienced this with any of my other conversions.

Chris.
