I know Mitsubishi did do a good small engine but how good are they compared to the Honda is another issue. What i have been quoted is the 3.5 Briggs with a 3/4 inch shaft new clutch half with counter balance. It's interesting that in the past my unit was re-engined with a Kawasaki FA 130d while a great design for a side valve, parts are just a pain in the a**e to obtain and those that are cost a bomb.
