Since this was the second time I installed the engine it went much easier.
The engine is set .125" higher than the secondary pulley wth a 0.5 degree aft tilt. Other builders with more experience state that the engine will settle this amount over the first 100 hours and as the drive belts are tightened over time the rearward tilt will be gone. The above is accomplished with a initial bet tension of (can't remember right now!!).
