150cc sidewinder sputters when given gas but the runs fine.
150cc gy6 sidewinder buggy, bought if off a gentleman a week ago and got it running. With the carb that came with it, but to start it I had to start it with starting fluid and then could drive it with just smoke and that was all. Well I replaced the carb and the choke and now I can start it without starting fluid and it will idle fine now but when I give it a little gas it wants to die but when I gun it she will go. Note it doesn't have an airfilter, and the vacuum lines are not there. There is a line from the valve cover that pushes air out but idk where it goes. Also while driving it it will backfire just a single pop every know and then. Any ideas.

Spark is good, smoke is just white but doesn't do it now with new carb. Compression seems fine, I took the top end off and rings are still good and cylinder. But no I haven't checked my valves.

Well I cleaned the carb just 28th carb cleaner but that's it. I haven't changed the jet so I'm not for sure on the size.
