Re: Water in Cylinders 3 and 4
Two cracked cylinders, unlikely. Crank seal wetting two cylinders also unlikely. Exhaust plate maybe, not sure how that motor's set up. Does that motor have a thermal carburetor regulating valve----no, that's not its proper name, but a valve with a vacuum hose that controls the idle mix based on water jacket temp. A total long shot, but if it were damaged it could maybe allow water to suck into the carb.--(?)
I agree that the cylinder and crank seal scenarios are unlikely. I will look at the exhaust plate again.
The only valve that I see in the manual is a bleed check valve. Here is what the book says:
" The bleed check valve allows excess crankcase lubricant to flow one way, from the bottom of the crankcase to the top end cap bearing to provide additional lubrication. Inspect check valve for proper operation by applying vacuum to outlet side of check valve (barbed end). No restriction to flow should be felt. Apply vacuum to threaded side of check valve. A restriction to flow should be felt indicating check ball is seating properly. If these test results are not obtained, check valve must be replaced."
I have not checked this, it does not make sense to me that if this were malfuntioning that water would get into lower cylinders.
I dont believe the carbureter has a thermal regulating valve. It does have a fuel enrichment system that we had to push manually to start the engine. There may be a short when we depress the key switch in as it does not appear to be providing choke. The fuel enrichment has a T connection that should deliver gas to both the upper and lower carbs. I will check this again.
Again this does not explain milky plugs, anyone disagree? or, have further comments!
