I got me a stage 2 blockzilla with a 33mm mikuni carb with a accelerator pump on it. It was ran in Michigan and is now in Texas. It runs really good but head temp is too high and it has a surge when I let off the gas To go into the corner. Acts like the throttle is getting tapped and it will surge if I hold the throttle halfway. I rejetted main jet from a 185 to a 200 and still seems alittle warm and it still has a surge at half throttle?. Should I keep going higher? i adjusted the screw on the very bottom which I assume adjusts idle jet? I run tillys on all my stuff but the guy insists on leaving the mikuni. If I can't figure it out in gonna put a tilly on it. Thanks
