My idle is always indeterminate...meaning...I have no idea where it's going to end up...on an extended period it's at 870-900 kinda lumpy...coming to a stop it can be 1000, fairly smooth OR 1300 real smooth...but a throttle blip brings it back to 870-900 kinda lumpy.

I think I have to get the idle set based on the Mikuni idle slide screws only....and negate any interference from the original throttle assy. BUT I haven't been able to find a combination which will allow that yet (considering I'm always backing off advance trying to get rid of knock/ping (see earlier post i.e. "what is Knock VS. pre-ign.)At 10 deg advance, it'll only run if I raise slide screws to maximum, I'm currently at 15 deg advance.

YES...my overflow tubes leak on shutdown...I thought that was what caused dieseling on shutdown...tried a pressure regulator...but it won't work without a return gas tank line...1970 doesn't have one...'71 does...if it's an "E".

Hey...who said this was going to be "plug and play"
