Also, food for thought......a 750 was too small for my engine. It would give a lean pop and hesitation at about 5500 rpm. I slapped an 830 hp on it and also a demon 850. World of difference. Now I shift it at 6k-6200 on the bottle. I am almost certain that carb is too small.....it might seem fine just cruising around but it will more than likeley bang out high in the rpm range. Looks like you just need some good old fasshoned tuning......I run an NGK #8 plug....mine likes those much much better than the R45 delco plugs.
