I recently suffered from fuel in the exhaust manifold, carburator and cylinder heads. I followed your instructions very carefully and used liberal amounts of Marvel Mystery Oil (MMO) in the cylinder heads and then some more in the fuel. I manager to get the engine started and it seems to run great when it is running but I am having some trouble getting it started and am looking toward the fuel pump for a few reasons. The reason for the water in the engine was that the exhaust pipe blew a big hole and allowed water to enter due to the lack of positive pressure in the muffler. A lot of sea water got onto the fuel pump and safety switch. A few times when I turn off the engine I hear a tick, tick, tick coming from either the fuel pump or the safety switch. Since the carburator is not filling with fuel during this event, I think it is the safety switch. If I turn off the batteries the sound stops immediately but will come back on if I turn the batteries back on without letting things cool down.
The hard starting sounds like it is turning over but no real combustion until a little while and then it starts up. In another related situation, after running the engine for about 20 minutes at idle, I tried to rev the engine and it wouldn't get past 1300 RPM without choking and dieing. I think that was due to a main jet that was blocked (with some crud from the past water event) but has worked itself out. Now the hard starting problem remains.
Any ideas on what to do first?
Thanks
