your best bet will be to start at about 22. that seems to be a nice place to start and many engines run great there,,,,,since ur not going for high rpms,,,and the rpm,s arent much more than stock,,,,u dont need a lot of advance...it should run fine at 22..23...the factory advance is 14 degrees on most of those pumps,,,

If you had to put your timing at 35 to keep the flame down you may need a new cam or one with a different grind. We run a 13 mil and a 15 mil and both are at 24 and we pull 3rd and 4th gear.....

I started out at 20 with my pump and turned the manifold cherry red. Bumped it to 28 and till had 14 inch flame. Did some checking found out my pump has no advance, moved a tooth and ran at 33 with still 8 iches of flame. Moved it to 36 and have got the flame to around 5 inches. Going to move to 38 and see what happens. But if your pump has advance that is around 14 degrees, so pull 14 off my 36 and your at 22. Only two ways to put out a flame on a motor without water and that is more timing or more fuel.

I ran mine at 36 degrees and could run road gear on a hard track, 3rd on a tight track. 14 degrees in pump.
