Re: 30HP johnson hard warm start

Well was in the process of "decarbing" today and engine started up first time-ran seafoam solution through for about 15 min. and let her set about 15min. Pulled it over to start again and it pulled considerly harder-never got it started. Pulled head off and cylinder walls look good. I did notice that maybe the head gasket could be bad. It looked like compression/exhaust could of been getting into waterjacket. There is some milky oily stuff on bottom of cylinder waterjacket. I guess this could be just a overheating problem?

Re: 30HP johnson hard warm start

Found out my problem was a bad head gasket-letting exhaust into waterjacket, overheating. It was also letting compression into my intake stroke making it a hard start. I also got the head machined . I want to thank everybody for their help,suggestions,opinions,etc. Thanks again.
