Re: Can't loose that ping
no, I'm not suprised but then again JeepsRUs have had success with them in
some cases. Since they refunded my 57.00 on that suggestion it was worth a
try. If I was stuck with it then it would be a different story.

Re: Can't loose that ping
It's running too lean, or too advanced. If you make it wetter, for
sure in will solve the ping. Have you tried increasing the pressure? The
regulators I seen run on the same diaphragm principle as an
oxy-acetylene regulator works, just screw the center pressure spring
in.

Unless they were referring to the fact that the ported head has the
combustion chambers polished, I don't see where a ported head would
eliminate pinging from an engine.
