Need some help. I believe I have a model "D" carb. It goes to a automobile engine. I have gone through the many threads on the discussion board and found many interesting items.
Tried to get the size by using NPT fittings 3/4" and 1" but found the 3/4" too small but the 1" was a very loose fit.
Does anyone make replacement parts for these carbs?
I didn't break anything but might like to replace some pieces that are over a hundred years old. The butterfly blade or plate is not in the best condition and the float may need to be replaced.
Any help and suggestions greatly appreciated. |

Otto gas engines sells replacement floats you can find hem on the web and your throttle valve is not the D type |

I think Schebler did make D model carbs with that throttle valve. I also have one like the photo posted and the carb is made especially for that throttle valve. the throttle valve has a machined shoulder that is made to fit into a bore on the carb unlike the regular D type carbs. Could have been a auto carb.
The floats from Otto (Dave reed) I believe are made of polyester and micro balloons. There is another company that makes Schebler floats from Nitrophil which is the most modern float material that nothing will effect it and it is super light. However the floats are expensive like $80 or $90 dollars. You can purchase your own material and make the float much cheaper. email me if anyone is interested. I don't recall the companies name know. |

I forgot to mention about the thread on your schebler carb. Can you make a new pipe nipple that threads into the carb? If so don't cut the threads as deep in the pipe nipple. |

Thanks for all the info.
I did make a mistake to the 1" NPT being a loose fit as it doesn't fit at all. Too big.
I am not sure about making a new pipe nipple. Appears to be in good shape. The original is tight in the 90 going into the engine. A few things I don't wont to mess with after all it is over a hundred years old |

Make sure you have a seal between the top of the throat and the cover otherwise the carburetor just won,t work right. Cork works well. |

Great! It currently is brass to brass and didn't think that was right.
I removed the throttle plate rod and the seal appears to be a cloth or rope material tightly packed. Anything special about this material?
I'm thinking about using an o-ring. |

Make sure the o ring will stand up to gasoline.
Shorten the male thread and it should fit the oversize female thread. |

Richard, The seal you are referencing in post #1116 is that the seal between the brass lid & bowl in the center throat? Must be about 1" or maybe 1-1/4" diameter just guessing? (Schebler 1" NPT D model). |

That is the area you must seal otherwise you won't have much luck with the needle valve etc. |

Just to update the links for Otto Gas Engine Works and Schebler Model D and Krice "doughnut" floats and some rebuild parts:
http://pistonrings.net/carbsche.htm
Schebler Mod. D parts diagram: http://www.oldmarineengine.com/technical/carburetor/schebler_3_image.html
The Carburetor Shop has some excellent application lists, but unfortunately no listings by carburetor rather than engine,(not that I could find anyway)
http://www.thecarburetorshop.com/Marinekits.htm
They only answer the phone on Mondays and Tuesdays (Central Time Zone).
It looks like a comprehensive rebuild kit for the Model D is not being produced? |

Dave at Otto can get most of the small parts for the popular size Scheblers if you ask. Caution! Some are pricey.
