So i have changed everything on this engine including plugs,plug wires,cap, rotor, coil and a brand new platinum duralast. The darn thing is still popping through the carb with vapors but only when you slam on the gas . so im asking for any suggestions on what it might be ? Or what engine should i replace it with and get the best bang for my buck.
P.s. Put a vac gauge on it and it just vibrates from 19 to 21 back and forth.
