| Post subject: | Carter 1611 on slant 6 airport tug |
I have a late 60's to early 70's aircraft tug that has a slant 6 with a B&B Carter 1611 carb on it. The plate on the end of the throttle shaft wobbles on the shaft and the idle speed is always changing. It is a pretty basic carb other than a manual choke with a linkage to maintain a higher RPM when the choke is on. I want to replace the carb before we accidently drive it through an airplane. Can someone tell me what will work that is available? Webmaster: I tried to register and don't get a reply back to confirm registration. Username: wingsaircharter |

I would find a carb rebuilder in your area that can rebush the throttle shaft. Made a world of differnce in my carter bbd. sb |

The slop isn't in the throttle shaft bushing. It is the plate that is pressed on the the end of the shaft. We don't have a carb rebuilder in the area. Hopefully I can just bolt on a new one. |

When you talk about the "plate on the end of the throttle shaft", are you talking about the throttle lever on the outside of the carb? That's the piece that the throttle linkage attaches to, to push the throttle open. If you have slop between the throttle lever and the throttle shaft, it will be difficult (and eventually impossible) to control the engine speed. And yes, if the throttle lever comes detached from the throttle lever, the engine will likely "run away" from the operator. Most Carter throttle levers are staked onto the end of the throttle shaft. If this staking has become loose and sloppy, the carburetor can be removed, the other end of the throttle shaft supported on a firm surface, and a dead-blow hammer and prick punch can be used to re-stake the lever-to-shaft junction. If for whatever reason this is not possible or not satisfactory, it shouldn't be too hard to come up with a workable carburetor for you. 1611 isn't a valid Carter number (it's probably a casting number — not the same as a carburetor type number), and the industrial/off-road applications used many different carburetor configurations. Some of them are similar enough to passenger car/truck carburetors that they can easily be replaced with car/truck carbs. Some of them are significantly different. If you'll show us some clear, well-lit pictures of the carburetor from a couple of different angles (including, if possible, a clear view of the problem area), I or another member will be able to supply you with a replacement carburetor, direct you to a source for a good replacement carburetor, and/or detail an appropriate fix. |

I wonder if you could solder the throttle lever on if it can't be restaked? |

I have successfully fixed this type of problem with a quick "zap" from a MIG welder. (Key word... quick, because you do not want a lot of heat to build-up) DD |
