RE: Advancing the Timing on a Homie
Ditto to what Mikenlapaz said.
I race Open 4-cycle gocarts.... (stock 10 hourse tecumseh tiller motors turning close to 35 HP!) We lap the flywheels to get the timing were after... works great! I would caution using the loctite method... as av8tor1977 stated it is VERY difficult to get the flywheel back off without damaging the crank.
