Dave,

I dont pretend to have all the answers in regard to your dieseling,
but .....

The dieseling, at least in my experience, is caused by carbon in the
cylinder that stays red hot and sets off the next explosion as soon as
compression is built up in that cylinder. A tank of higher octane gas
will sometimes help. A cup of ATF down the carb can help get rid of the
carbon in the cylinder. Sometimes putting in new and correct plugs will
help. Autolite 85s are the ones I use, thanks to the digest gurus.
