Default Re: 1996 g-14 low rpm

The TCI advances 32 degrees or something over 2500 rpm. When mine would get hot (typically in hot summer weather) it would act funny at low rpm like it was bogging or something. It would lose maybe half its power. One day I was up a backroad a couple miles I said fine, held it on the floor for quarter mile going 20mph or so and all the sudden it took off and actually stopped doing it mostly after that (though it was still down on power when hot). It would run 28-30mph gps on flat ground normally. However it was getting tired so not sure if it was a valve sticking or just loose cylinder or what it was. Always ran synthetic and it never did it in cool weather or when cold, only did this last few years I ran stock engine (never rebuilt, replaced by clone last year).
