This carburetor is said to be the original off a Hicks single-cyolinder engine made about 1926 (we think).
Can you identify the model? And where we might find information on its operation.
The carburetor is apart because we are going to attempt to scale it to 1/4 size for a 1/4-scale Hicks project

Check out the Schebler Model D under the TECHNICAL heading on the cover page this site. I'll give you the missing parts for visitation rights! I need bolt hole spacing dimensions. |

You are most welcome to visit. What dimensions do you need? I probably have it in our working sketchs.
We have more parts than this. In fact, I think we almost have a complete carburetor. This is just one of the pictures I took so the fellow modeling this in 3D can see how it should look.
What we do not have is the choke plate. At least that is what I call it. Someone had cut out a piece of tin can and put it in place of what I assume was a brass plate or casting. Pictures or a sketch with dimensions would be a great help.
This is it as we made it:
We'll have a full set of drawings of this carburetor as part of the process in reproducing it in 1/4 scale.
We always start out with the models at full-scale so we can check dimensions without any mental arithmetic. So those should be available too.
Also, the San Francisco Maritime Museum wants a set of drawings (engine and all) suitable for their full-size engine so we need to have full size anyway.
This particular engine and the modeling process is taking place in Vallejo, CA which is at the north-western tip of SF Bay and about 14 miles from the Napa valley. |

Mike,
Could you post photos of your Hicks ? Dating it will help identify the applicable accessories !
The Hicks engines up to 1924 were a different design than the later Yuba Mfg Co.engines-- both great old engines but different ?

OK, here are 3 views. I don't know enough about Hicks engines in general to know if these views will tell you what you want to know. But I bet the Label Plate will. That is if it is the original.
I think this should do it. You will note the non-standard intake and exhaust systems on the engine. We would like to obtain information on the original components so they can be included in the engine design.
Thanks for your help. |

Another request:
We have the water pump for the engine and the eccentric is in place on the crankshaft but the connecting rod from the eccentric to the pump shaft is missing.
Would really appreciate a picture or two and some basic dimensions of the rod.
The water pump looks like this in case there are different pumps. This picture was taken before the pump was disassembled and cleaned. Were they delivered from the factory with about 0.05" clearance between piston and cylinder wall? This is measured where the parts are not apparently worn.

From the Moderator:
Mike. Probably best to leave it here now. No problem. Thanks. Andrew |

The Hicks engine above H 9028 although having a Yuba Tag on it is the old style engine from 1890's into the 1920's. These engines had the cams and maneto drive shaft at the rear of the cylinder at a 90 degree angle from the crankshaft.
The Yuba engines had the cam shaft and mag drive on the starboard side and the cylinder had a square shape to it. Yuba also made multi cylindered engs!
Yuba Hicks Single
The Yuba Hicks H 9028 is a later version of the original style hicks and the quick way to tell is the width of the tail shaft support- the early engs being much narrower.Eng in left photo
1908 ca.
 
The date on H 9028 of 1926 would be close or within a few yrs untill more info is discovered ?
I have the waterpump off of the older eng in above photo and in next week will try to photogragh the connecting rod and measure for you- will post back here !

Thank you, Richard.
We hope to have a date-accurate model of the Hicks when the project is finished. That is why I am looking for all the little details that make the difference between a model that runs well and one that also looks the role.
I'll pass this all on to the other folks in this project. |

These old Hick's were Known as "conversation engines" when standing near one running at 350 RPM- in between cylinder firings you could hold a conversation !!
