Re-check static. Advancer is mechanically locked to the cam w a pin or key or something?  So, it cant slip on cam.

Yep the points plate and advancer is almost identical to my 360 just with one less point. Gap is smack in the middle of spec.

I know its too retarded. But that is what the timing light is telling me. Which is why I think that something's up.

The advance setting on the timing light should be at Zero, yes?

Check your advancer springs.  There should be pre-load on them.  If they're stretched, you're losing advance and thus bogging and losing power.  It can also cause hard starts and rough idle.

Buy an old two stroke so you just don't deal with timing chains, valves, or advancers.

I'm thinking this may be where my problem lies. I'll pull the advancer out of the parts motor bin and compare.

If I grab the advancer lobe on the cam with my fingers and try to rotate it there is some slop there.

There's not enough tension from the springs. I don't think they're sold as an individual part, though.

I took the advancer off the parts motor, it's a different design with different springs. Seized, going to rebuild and try swapping it on.

I've gotten away with removing a coil- basically cutting off the pigtail and pulling one coil to become the pigtail to replace it.
