Billet flywheel install

[sdkid]

I bought a used billet flywheel for my 5hp. I believe it is from a 3hp engine. As I look it over I see it has no keyway. Haven't found anything online about how to time this to my engine. Does anyone have any ideas, or a direction to send me in? Thanks all, Chris....

no keyway? what brand is it?

you must use a degree wheel to time it,or use the in the hole method.
i made a piston stop with 3/4 square stock,that has the cheepest 5/16 bolt in the center that acts like a piston stop.this is bolted to the head surface,with a head gasket it makes the piston 27 degrees into the hole. without the gasket it sits at 32 degrees.
have the magneto on the engine and set close to flywheel,about .035 away. align the left side of the flywheel magnet to center of the pickup on the magneto,which is about the center of the right side leg of magneto to right side of the flywheel magnet.with my piston stop i can either set a degree wheel up,or just use the 27 degrees of the pisto stop.with gas use the 27 degrees to start.
hope this helps and is not confusing.

sorry,its supposed to say right side leg of magneto outside edge to right side of magnet.

All the flywheel says is "Fast Times Inc". Would anyone know if a degree wheel is a degree wheel? I have access to one for V-8 engines, will it work?
