Full vacuum advance at idle is OK but must be unhooked when setting the timing. If the timing & all is ok your carb probably is not right. "New" carb usually means a reman & about 3/4 of them are not right. Make sure the accelerater pump has got a good shot. Or the float level may be to low. Are you sure the plug wires are on the correct cyl.?


They say money can't buy happiness. It can buy old Chevy trucks though. Same thing.
