The saga continues....
I removed the hot section from the manifold yesterday, and the engine started right up. It started with unbelievable ease. Thus, I thought the problem I was having was the result of a blockage in the exhaust system. As I searched for the blockage, I tried blowing on the wire/rubber exhaust hose, and couldn't blow out. I took the hose apart where two sections meet in the port lazarret, and blew on both sections (forward and aft). The aft section was completely clear, and the forward section ejected a significant amount of water into the cabin. When I hooked everything back up, the motor started right away, however, with more difficulty than when the hot section was removed. I opened the raw water seacock, the muffler lift and hose filled with water, and she continued to run. But it was struggling.... Finally she petered out....
Other symptoms the engine is experiencing:
1.) I have to continuously prime the fuel system with a priming bulb, even though I've established that the fuel pump is operational. Also, I've replaced all of the fuel lines, the priming bulb, and removed the gate valve above the take-up tube (as I've heard they are often the source of air leaks).
2.) The sparks are completely dry after trying and failing to start the engine.
3.) Compression is 91, 76, 92, 60.
4.) There is plenty of fuel in the carb bowl.
So what could be causing this engine to fail to start?
Could there be too much water in the exhaust hose, or a relatively small restriction that is causing it to pool and create back pressure?
Once again, I appreciate everyone's help.
Best wishes,
Dwight
