Check the canister control valve next, Thats the thing that is next the the

fouling,
This is in response to a person who had the pinging problem, so these
things in order to check for symptoms. I think it was Kenichi, not sure
Chris 92 classic.
Also the crank angle sensor is controlling the Timing part too, that
may be bad and you have to replace the distributor for that! Hope that is
not the thing
