massive reconfiguration time again.

I forget...what fuel is this? Just straight pump gas or a mix? This plug has the total timing looking good, but I'm having trouble getting a read on the initial.

It looks a bit rich at idle still and probably cruse too. If that door isn't opening, I'm not sure what that does to the fuel curve. No air, no fuel flow. But it has to be screwing with cylinder to cylinder distribution.
It seems to have decent low throttle response but when I get into it it definitely has a bad hesitation. I tried letting the door open a little faster and that didn't help and then I tightened it a little bit and that seemed to help but I haven't given it enough test tries to see if I need to do it more. What really gets me is when I do get the RPMs way up and then I throttle back it really seems to run like crap on the throttle back down to cruise...???
