Re: Johnson CD-13 trouble shooting.

Well, I for one, kinda think it is a good sign that the engine doesn’t want to die out to quickly when the throttle is completely retarded to the stop position. This engine must idle very well at low throttle settings, or else it would die out easily with the timing retarded. I suppose the throttle linkage might be messed up/stiff, causing it not to retard the timing enough to shut the engine off.
In any event, I don’t think the two "symptoms" are related.
