The symptoms you describe could also be a bad accelerator pump or the linkage on the accelerator pump needs to be adjusted.
When I rebuilt my carb there was a dead spot on the throttle right when you'd take off. I found the accelerator pump had too much slop in the linkage. I reduced the clearance and then the hole shot was instantaneous. |

Yeah, I think I may have a vacuum leak already from running it with the missing nut for so long. At the end of the season I will probably take the carb off, check for flatness and reinstall with a new gasket. For now I'll make do.
It has problems on take off. If you "floor it," the engine just dies. If you ease into it, it does fine. I also experienced some sluggishness at full throttle. I was pulling a barefooter for the first time a few weeks ago, so I was pretty much at full throttle. Ran great for a few runs, then started losing power at full throttle. I'm also changing the fuel filter, which hasn't been hanged since I bought it. Thanks for all the help. Like I said, you guys seem to have the best thing going. |

Yep, not too tight. Over tightening can warp the carb base plate and lead to vacuum leaks, etc. Just snug her down.

I use my calibrated arm and get it "about that tight". I've never been able to get a torque wrench on mine so I just snug them up pretty good, being careful not to over torque them.
Usually carb studs are 5/16" and the standard torque for a Grade 5 5/16" nut is 18lb-ft. I'd say don't go any higher than that. |

Not a CC owner, but you guys seem to have about the most helpful forum going. I have a '71 Century Resorter w/ a Chrysler 340 (great boat). One of the nuts holding the carb to the manifold has been missing for the three years I have owned it. I finally got around to getting a new nut, but was wondering how much this nut should be torqued down. I assume that it would be the same on pretty much any V-8.
Thanks. |
