It's perfectly normal for it to miss when you lean the highspeed needle, where is the airbleed screw set, it should be about halfway across the airbleed hole. How is your tank positioned in relation to the carb? I'm asking a lot of questions but these are things that I take into consideration when setting up a Diesel conversion, I have an LA .46 and a LA .65 conversion so I know the LA is a good conversion cadidate. When you ran it as glow did it hold full throttle without the rpm wavering up and down?
