I got it running via pullstart, now it spitters and sputters when i put full fuel to it, and will NOT idle. I crack the throttle when being pulled and it purrs like a kitten. Just have to hold the throttle in the same position. I got the engine to rev a few times but would just sputter out and die, I got it going via starting fluid w/o pull starting it once. Where do i look for now? Is it my float setting, or is the distributor getting out of time? I have the retainer nut broke loose so i can adjust timing easier.
