I have a 1988 Chev 305 engine that acclerates on it's own when I am trolling. I tap on the throtle to get to the correct speed 4m.p.h. It stays there for a while then suddenly speeds up on it's own. It also does this when I am running at higher speeds at times. This never happened in the past and seems to be ge3tting worse. Any ideas? Thanks in advance!!!!!! Art
