Figure out a way to determine your A/F ratio. Should be 14:1 at idle, 13:1 midrange and 11.8to 12.0 wide open. The only way to determine this is with a meter. Everything else is guesswork. Good Luck.

Exactly correct as long as you are not too close to the edge of detonation with the engine build/boost.

The gears can only go on the rotors one way and I see marks on the gears but if you line them up the rotors would hit. Thanks

You have to line up the marks. The gears are mitered so the rotor will hit until you get the gears seated to one another. Fine tuning of rotor timing is done with shims under the miter gears. Make sure those go back just like they came out or you will need to retime the blower.
