any suggestions for a good 12v source? I get 7V the way its now connected...
BiggumYou need full 12v to that choke - 7 won't cut the mustard. Here in Maine I have to adjust the chock for winter or summer since the temp swing is so drastic. The linkage can also bind up causing the choke to stick closed or sometimes the high idle eccentric doesn't drop down the way it supposed to when the choke is open.
Old school trick I was taught was to adjust the idle so that the transition slots in the bores form a square against the butterfly, then adjust your idle mixture and timing to get the idle where it should be otherwise you are just covering up some other issue by adjusting the idle speed screw.
