I�m having problems with soot build up on my spark plugs in my M-60. I have tried Autolite 386, Champion D16 and D18Y plugs but they all soot up and then the engine runs rough at low revs and won�t idle well like it did before my rebuild. The engine definitely runs much cooler now. Should I adjust the carb? Any suggestions would be appreciated. |

sounds like the mixture is far to rich, there is a adj. at the bottom of the carb if you are still using the original zenith.
you can call if you like and chat 707-312-1774 |

i sent you a mail ben, you restored the compression and it's pulling in to much fuel. very typical problem when you rebuild an engine. the carb had been adj to be rich because of poor compression, also the temp of the head on an engine can effect firing efficiency, doesn't probably apply here tho. |

Hello Everyone- I just bought a 1972 30ft Columbia with a Palmer 60. I am changing the spark plugs and was told to use Champion d15. I read through all of the postings concerning plugs and have gotten different gaps. One says .035 and my Napa store says .05. Can anyone tell me what the correct gap is? Thank you in advance. |

Gap is .035. Champion D15Y is a marine plug. Autolite 3116 is easier to get and costs less and will run beautifully. The D15Y has a more corrosion resistant steel in it's base. That is the main difference but unless you leave them in for years on end it is not needed. In either case use antisieze on the threads of the new plugs when installing.
Be sure you understand where the Palmer P-60 and IH C60 are different when ordering from Napa or a tractor shop. |

Note: The size of the plug is 7/8 inch industrial plug. |

The d series of plugs are 18mm. 7/8 is much larger. |

Let me put it this way. When I went to change plugs the first time, not being familiar with the Palmer P-60, I took out the 13/16" automotive plug socket. It would not go on. A friend of mine, a mechanic, said that it must be a 7/8" industrial plug. I then purchased a 7/8" spark plug socket. I dunno. Been working good for me. |

Thats right wrench 7/8 and threads 18 mm. They are listed in the parts books as 18 mm. so that is what you would ask for. |

Larry, OK, that makes sense. Thanks for the clarification. |
