Blower surge Make it stop

Heres with timing locked, before uploading the custom timing map I made. I could have leaned it down , but the idle speed would have had to been around 1100-1200rpm to keep her running.

Being able to idle at a lower timing setting in nuetral, and higher timing setting in gear, makes for a much larger window of tuning your idle setup.
So, when you backed the idle timing down to 10*, and she was at 850rpm, she'd stall when putting in gear. What if, you were to try that again..back it down to 850rpm with 10*, and back the mix screws out slowly, till it just begins to surge., then, crack the throttle blades just enough, to get it idling at 950-1000rpm. Ill bet the situation, will be much better.
What kind of advance setup do you have? Weights and springs?

MT thanks for posting the videos very cool. So if I start to back them out at 850 @ 10* it will take off and surge as soon as I touch the first idle air bleed an 1/8 of a turn. It is way sensitive big time. This is the issue Ive been having with it. There is no curve the distributors are locked. So when I back it down to ten thats all the timing all the way as you would know!

At 16* I think we were able to get a little lower rpm and still idle nice and better AFR`s but in the boat I had to richen it up a bit to mid 12`s and add have it idle at 900.
