I`VE GOT A 45 CC STIHL THAT CAME OFF A NEARLY NEW CHAIN SAW,IT WAS CONVERTED BY SCOTT ELLINGSON AND IT STARTS EASILY AND RUNS WELL.
I`VE GOT IT ON A HOSTETLER 33% TRIPACER AND MY QUESTION IS ARE THESE MOTORS MORE LIKELY TO VIBRATE MORE THAN A PURPOSE BUILT ENGINE? AND IF SO, SHOULD I BE LOOKING TO DAMPEN IT WITH SOME SORT OF RUBBER MOUNT? RCM

From my experience, one type doesn't vibrate any more than the other if the engines are the same size and type.

Vibration mounts often create a new set of problems.
