Do you have a NT carb? After running Opti at 100:1 mine was 4 stroking a lot with the stock jet, I installed a 68 and it improved it the issue slightly, then I switched to a 66 and it runs way better with just a bit of 4 stroking at about 1/3 throttle and again at about 2/3. I may order an even smaller jet to see if that will eliminate the issue altogether.
