Well I have just wasted 2 days trying to modify a G4 carb so I could get it to work the same as I do with the modified LM carbs. I have tried and tried to get the idle down to where I wanted it to sit but no matter what I did the idle would not lower. Finally I admitted defeat, and I put on an untested modified LM I already had sitting there and inside half an hour I had swapped them over and it now works perfectly. I cannot understand why I can't get the G4 to perform the same as the LM's. I kept trying because I believed I could master it but I admit defeat on this one. I have another G4 here so I will eventually have a go at that one to see if I can get that one to work
