Ok, guys, thanks. I am running a NGK CM-6 plug. I also tend to think the cab is not pumping. I rebuilt it on Sunday with a Walbro kit from my local Auto Parts store. (Diaphragms only). Now with the new RCexl Ignition and new Hall sensor I have no doubt that there is good spark at the proper time. So it's has to be fuel right?

After running on the choke for a second. After I open the choke it will pop and sputter. Engine gets warm, didnt notice any smoke. I'll try again today. I have both needles open 2 turns. I'll close the low speed down to 1 1/2 and see if it makes any difference.
