Having just rebuilt my stock 1500sp engine in my single cab,its now done about 200miles but i can't seem to get it running perfectly,have checked timing,valve clearances,been through the carb but still getting same problem. It runs fine but when i go to pull away or change up gears then put my foot on floor its jerky,stutters etc till i whack my foot flat on the floor! I replaced the heads with other 1500 heads & these had larger inlet valves,would this of made a difference? would i need to put a larger jet in the carb now maybe? Any ideas appreciated thanks,
