Hello everyone,
This is a whacky theory, but I figure no better place to get it shot down by those more experienced than me, so I can move past it and onto what the real problem is likely to be... so here goes:
I think that after sailing for at least an hour, and with substantial time heeling on Port tack, the fuel level in the tank (starboard side) can be lower in height above sea level, than the fuel level in the Carb and Mech fuel pump, and the result is that while sailing like this, the fuel slowly siphons out of the fuel system and back into the tank.
Ok, that's my theory based only on having starting issues when starting the engine after a good sail. Ie: the engine has to crank for quite a while before firing. I figure its caused by fuel needing to prime back through the system. I tested the Compression and Spark, and they are normal.
What do you all think??? Is this reverse fuel flow on Port possible (fuel tank is on Starboard side, and at rest; the bottom of the tank is probably around 4 - 6 inches higher than the carb/mech fuel pump), or is the system sealed and unable to flow backwards???
Anyone else experience similar starting problems after sailing for a while???
Let rip!
Thanks,
Ralph.
