I used a crank from a 11hp horizontal engine.

Never though of something like that. How did it work and did you use the flywheel also? Scott

Recheck the balance and adjust as neccassary, posted on here several times on how to balance.

There are alot of questions about balancing engines.
As huffy said, CHECK IT!
It is always best to check an engines balance no matter how "proven" the practice. The smaller the engine, the more important little differences are. A small difference in weight is a higher % the smaller the engine gets and the faster you turn it!

Could be why His engines wrap tighter than panty hose on a line backer and stay together...!

I used the stock 11hp flywheel but I believe the ARC flywheel will fit under the 11hp blower housing, as far as balancing, it had a slight vibration at idle but at race speed it was just fine.
P.S. you don't need to turn it over 6,000 rpm with the right Isky cam and some carb work.
