Ok the full story here. I got a new 2cycle engine I put on a frame. I got it running only to find a vacuum leak around the intake at the cylinder head so I try to tighten a little more and end up stopping the threads in the head. So I drill it out and tap to std thread. I install the intake using a new gasket and used 3M gasket maker just for insurance sake. I used the short intake after making sure it was flat by using Emory cloth on a flat surface on the intake. I get it running and it idles great and has good throttle response up until half throttle and above. It just noses over and every now and then it would backfire out the carb. So someone please tell me what I am missing here.
