    How many spark pluges does your engine have? Then we have a clue as to what motor we are talking about!

    Just as i thought! Adjust the carb. check point gap and choke stove. Heat riser may be stuck. Vacuum advance inop.
    Centrifugal weight springs can be changed so mechanical advance override is prevalent!
