Hey guys its been too long, but I'm back at the blaster ok so here's the prob. I got a motor built by ken oconnor ( did a great job) and I'm running a 34mm keihn carb. 45 pilot 155 main dgh needle. I have to choke it to get it to start and when it does it runs wide open when I push the choke in it goes dead unless I blip the throttle but when I do it runs wide open again it wnt even attempt to idle or run mid throttle its wide open or nothing I did an air leak test and found no leak so I'm stuck. So I'm asking for help from you wonderful blaster brothers thanks
