Im getting some popping out of the exhaust as well, but this may be due to a lose exhaust clamp, which i will be replacing next weekend.

What ever happened with this? I am having some similar issues but for different reasons. I rebuilt my 1800 adding a Scat C25 cam. Had to switch to some Weber ICTs as my Solex carbs are a mess. The similarity I am having is the lack of idle. The engine runs great but won't idle unless I turn the speed screws in 3 or more turns. Currently at 60 idle jets, 140 mains and 160 air. The pump jet is 50 and exhaust is 40.

Was your problem with idle a jetting issue?

My problem was there was crap clogging my idle jets and pathways. The accel pump wasn't pushing out any fuel. I got really fine wire and rooted it around and cleared all the paths and jets out. Solved the majority of my issues. I never figured out how to jet the carbs perfectly, but I have been running them since all the issues went down without touching them again. No issues. Still getting around 30mpg
