Alan,
I put an eddy carb on and it runs better and is getting much better gas mileage. however, it changed up everything else that we did. i am just trying to get it to not ping now. i think i may have a bigger problem now. the rear end sounds like i am dragging chains. started hearing it when i got back from your place. will have to check
Hemiken,
which coil? i just upgraded to the MP electronic distribuitor.
