The SC maxes out at sub 3,000.

You are 8-9 degrees past max timing at 31.

You sure you know what you are doing?

Sorry to be a killjoy.

Go to 2500 rpm in 3rd, slowly floor and listen for spark knock with windows up. If no knock, keep advancing until you can hear it, then back off just a tad. They are all pretty sluggish until around 3500 rpm. If sluggish after that, might need to check control press. to make sure your not to rich. Valve adj. no big deal. 4mm is pretty easy to gauge by feel. If the gap feels good, leave it alone. Main ones you are looking for are ones that are to tight

Thanks Don, will try that in a.m. I am running a mix of 50/50 (93/105 octane) most of the time it is 93 but I put alittle Avgas in this last time.

Keep in mind my head is wrapped around the US 87 octane SC with the wimpiest advance one can imagine. 18-23 is the spec and there is not an official @6,000 number to reference, regardless of what folks say.

I have said previously go to 25 if you feel lucky. But I am Super Chicken.

I am on your side, trust me. I know I am leaving throttle response on the table.
