I think Kook's a happy camper Nice cheap easy fix
Just goes to show ya' what happens when you post pictures It would have taken a long, long time to get to the same end result without pictures. So I guess I wouldn't have seen that the O ring was missing if Kook hadn't taken some pictures and he wouldn't have done that if Dreaming hadn't brought up the idle screws one more time and on and on, lots of people...................CCF teamwork again. I guess it's another case of "when you think it's ignition, look at the fuel system and when you think it's fuel look at the ignition..............unless it's totally obvious what the problem is. Surprising how many times that works.. That missing O ring also may have brought back some not so good memories for me by the way, if ya' know what I mean |

That was the first thing I thought of after you described the exact symptoms of a missing O ring ! One of those "been there done that's" Still Ken, I admire you catching it. |

If somebody is reading this and saying "I don't remember having a transfer tube" in my carburetor, Holley didn't come out with the tube till the mid 70's.
4160 carbs before that just had a hole in the metering block that aligned with a hole in the carb body and the metering block to carb body gasket had a hole that lined up with the other 2 holes. The holes were about 1/8 of an inch or so After that came bigger holes and the tube with an O ring at each end and a gasket cut to go around the tube. Here's a picture of the 2 different gaskets They're the same except for the hole for the accelerator pump discharge. You can turn the old style into a new style with a punch and a razor knife The bottom gasket in the picture was trimmed (not a great job but it worked) Some rebuild kits come with both style gaskets and also have the O rings that you don't need with the older carbs |

KooK, your engine runs great now thanks to Keno.
Modern Moly Rings like to break in at a 60-80% load. They will seat in 5 minutes run time if your cylinder wall finish is good. Boats are perfect for breaking an engine it because they are always under a load. I would take it out and run it. Vary the RPM constantly. I am not afraid of going wide open with a brand new engine after the 20 minute run in but don't keep there longer than 5 seconds or so and watch the temp and oil pressure like a hawk. If it starts getting hot shut it down and find out why. RPM in a boat wont hurt your break in but overheat sure will. Have some fun on the 4th of July, make some noise with your Toy. You pushed such long hours to fix it I suspect you had plans this weekend. Go Enjoy it! |

Yea, but somebody named Dreaming swung things back around to the carburetor and got Kook to take those pictures So I guess I'd say nice assist Kris |
