Top Transfer port cover gasket blowing,
Hi:<br /><br />I have recently purchased a 1965 Glasspar Avalon with a 1965 Mercury, 65 HP, Merc 650, 4 cyl. Serial # 1803488. My good friend (Forrest) and I have been trying to get this motor back on the path to stay with the boat. Most boat yards I have called, don't want to bother with it, because of it's age. This is what we have done so far. We have cleaned and adjusted the points, checked out the electrical system and appears to be working OK, good spark to all four plugs etc. Rebuilt the fuel pump to each carburetor. We recently re-time the engine, although we didn't have all the proper tools, we feel we are as close as you may get? The engine sounds good and then shortly thereafter, this gasket blows. <br /><br />Our problem appears to be that the "top" <br />"Transfer Port Gasket" keeps blowing out on us, happened about 3 times so far. We have replaced it and the cover appears flat and we even cut the gasket oversized to possibly help. We haven't used any gasket cement on it and don't know if that would help.<br /><br />The bottom one seems to be OK and we haven't had any trouble with it and it appears intact.<br /><br />Any commments and thoughts as to why this is happening to the top 2 cylinders only would surely be appreciated.
