So I have a sparta foxi. And i have a puch bullet coming, and I have a 14 mm bing carb and a high flow airfilter. SO when I get the exhaust Im gunna put on the carb, airfilter and exhaust. The carb has a 70 jet in it right now. Should I go bigger or smaller. Any Idea on what size I should go. The carb was running on a stock puch cobra before.
