Timing ok now. I am now checking main gets. What would be the perfect Air Fuel Ratio graph to see on the LM1 between 2000RPM and 3000RPM ?
I tried several jets from 145 down to 130. The 135 stayed between 12.5 and 13 at both rpm's. The 130 jet stayed at 12.5 @ 2000 RPM but jumped to 14 and stayed pretty constant at 3000 RPM. I'm not sure what to look for.

135s look good. 13:1 is a good place to be. Be sure to check wide open too. How's it running now?

I changed exhaust gasket in passenger side today. No popping on that side yet. I am now going to change gasket on drivers side and see. I will try to do a drive test later today or tomorrow. I bought a set of the alumniun exhaust gaskets. I am told they are guaranteed not to leak. They cost $49.00 a set so I hope they don't.
