Infuriating sporadic problem with water getting into the carb. I've been trying to figure this one out for some time as it's inconsistent but when she wouldn't start again today I knew exactly what to do and drained the carb to find the offending brown water drops coming out with the gas. I have meticulously been through the filtration system over the years and found no problem there. (I have three filters on the line...1 Sierra, 1 racor and just before the carb there's an inline. So filtration is well covered!) I have tested the gas coming through and no sign of water.
It suddenly occurred to me that maybe there's a hairline crack in the manifold that is allowing a small amount of cooling water to drain back into the carb through the port when the engine is at rest. Any thoughts on this? The water is brown.
When the engine runs, its just fine with no lumpiness that might suggest water.
I'd prefer not to pull the manifold but if you knowledgeable guys think that may be the issue then I'll go ahead and get it magna-fluxed.
Thanks...John
