    engine mount cups?

    Rusty, the new(er) 912's with the Soft Start ign ain't that bad on start up. The older modles were so bad it wasn't uncommon to shake off a carb or two.

    How do you tune the engine?

    Proper EGT, CHT and Tach is used to determine what if any adjustments are needed. I have a line of props that are less than 400 bucks and ground adjustable. 66" max diameter.

    Biggest issue with the 670 is the exhaust system. Theirs at least on guy out there claiming 80 - 90 HP and still only turning 6500 RPM. The snowmobile racing crowd is a good power source. Trust but verify. The stock 670 internals are fine.....you'll need a 4 to 1 gearbox.
