Offset Timing On Tecumseh

[GoAlterBridge]

Thank you all for the input, I didn't expect this many responses! I may actually try Coycaller's suggestion, and see how that goes. If anyone else still has some suggestions, by all means post them!
Thanks.

Edit:

I may also try toofarnorth's suggestion, too! (In the link I posted, I think it said something similar to elongating the holes.)

...What I would do is file about .020" off the flywheel key (left side, facing the end of the crank, and off the top part only if possible), then rotate the flywheel in the normal direction of rotation against it while tightening....

I have done exactly this on a GX240 (which nobody seems to make any performance parts for either), and it made a world of difference. Actually, I did 3 things at one time, I did some clean-up in the intake and exhaust ports, smoothed and polished the short turn radius a little in each, shaved about .050" off the head, and did the timing mod, it felt like I almost doubled the power, and definitely added about 1500~2000 rpms to the top end.
It turns right at 6000 now,

Wow, that's awesome... Maybe I'll do something like that... As long as I get the correct offset, and nothing will break, I'm fine with whatever type of mod gets me there.

Crankshaft keys are easy and cheap, might wanna buy 2 or 3 for it, and experiment.

Alright, I think I might do it.
