Hello, I recently bought a 3hp JH-20B outboard as a kicker for my sailboat. Thanks to a lot of previous postings I have replaced the ignition system, re-built the carburetor, replaced the impeller, cylinder head gasket and spark plugs, cleaned out the gas tank and fuel filter (fuel now flows well). I also chased out the crud around the cylinders to improve the water flow. (Many thanks to this posting http://www.outboard-boat-motor-repa... Johnson 3 HP 1952-1967 Tune-Up Procedure.htm)
She now turns over for about 10-20 seconds then dies. The carb floods and only starts with the choke open. Also I do not see any water drops at the relief holes so I am concerned about overheating.
The float valve is shutting off fine; I blew air through the fuel line into the carb and it went through fine and stopped when inverted.
Next week I will replace the orifice plug (part 39) and air silencer plate (part 9); both were missing. Will this solve my carb issues? Also how can I confirm if the water is flowing up to the cylinder jacket? The water tube is clear.
Thank you for any help with either issue.
