1500rpm Miss/Surge????
Okay so I have a weird problem. i'm getting a miss/surge from idle to 1500rpm. I cant figure it out. My buddy thinks its carb related, I think its spark related, its really ticking me off due to this being a new engine. After 1500rpm, theres no issue. Here ar ethe specs on the engine, please help.
