L-jet will run fine on this combo with a WEB 73 cam, but you may lose the warm-up idle on start, so it will start sort of like carbs.
You just need to give it a bit of gas, once warm it runs perfectly.
Sorry for the HIGHJACK:
Mark, I have this problem. 1911 with 9550 cam, 1.8 heads with 2.0 size valves, L-jet (AFM has been tweeked several teeth) and it does not want to idle until I get to 300-ish CHT. After that, it idles ok.
From your statement, it sounds like there is no way to fix????
I didn't get to play with it enough, members car not mine, it would stall at the first stop sign, but at about the time the pistons stopped slapping (3-4 minutes) it runs like a champ.
I was thinking it was cam issue (WEB 73 or a 9550 don't remember) combined with the increase in displacement. It was a non-issue as the member was willing to live with it because the car ran perfect once warm and he lives in a rural area. Also it only did this when stone cold, park the car for 2-3 hours and it didn't seem to have the problem.
