I'm contemplating to purchase the chariot performance 2 into 1 intake kit. Just want to know what carb to get. my motor has stock crank, 66mm pistons, boyesen reeds, pro design coolhead, CP pipes, plus 4 timing, 34 Pj with a drag port. I'm having problems with the left cylinder not working right. keep adjusting the float level and it will run great for a few weeks than no power again. which carb will I need for my set up ?
