It seems to be an electrical problem...

Idle, and off idle are probably the easiest on the coil, the coil works harder as advance and rpm come up..
and generally works, or doesn't work,, (but may crap out at hi rpm), - but at idle,, I think problem is carb related..

How about the accelerator pump, after the choke opens,,

Are your stalls, just as you give it gas from a stop, does it "hesitate" then go??

If you kinda boot it from a stop, does it go "pop" and die, or hesitate a bunch then go like he$$

"Stutters" from stop, but after the stutter, it goes good? accelerates smoothly??
