jim;
not enough initial timing and slow coming in. Should be all in by 2 to 2.5K rpms. Not enough initial lead causes many issues, not enough time to complete combustion before exh value opens, result burning eyes(raw unburned gas) at idle, you richen to attempt to fix idle, gets worse. Extra unburned gas results in a lot of burning going on in exhaust ports and pipes which results in additional head BTU having to be dealt with. Go to foursecond.com.. They have excellent tuitoral on this under tech section. Bottom line get ignition sorted "first" before even thinking about carb. I wasted a yr chasing that rabbit.
