Rockter.. I actually had the manifold off last year and had it dipped to clean it. Also stuck wires in the two ports. Anything else I should do?
Sailing Dog and Camaraderie.. How long can I leave vinegar in there? Can I put it in one weekend and then come back the following weekend and start her up? What bad things can happen to the insides (gaskets?) from muratic acid and vinegar? Don't think this engine has been opened up in a long time.
