throttle arm to carb I am confused about how the hand control is connected to the carburetor. I have looked at a few pictures of engines on Hemming s and it appears that the linkage passes through or below the engine. On my engine the linkage passes over the engine to an arm that transfers the movement down to the card. Crazy looking but it sort of works. Can someone post a picture with a close up of how a 23 carb should be hooked up? Thanks, Ed Saniewski

Re: throttle arm to carb It passes through the center of engine and out a hole in valve cover,or through the center of the two valve covers. On the vaporizers it went over the top.

This is a 1915. Your 1923 is the same except it has one long valve cover with a hole in the center for the throttle rod. The over-the-top linkage was used only in 1927 for the vaporizer, as Jack mentioned. All other years have the rod through the center.

Re: throttle arm to carb My valve cover is one piece across, and I did not see a hole in the block on the left side. I wonder if the engine in my car is a 27? I will look again for the hole. Was the "vaporizer a type of carb? Thanks Ed Saniewski

Re: throttle arm to carb Yes, it's the one they used in 1927. A lot of folks replace theirs with a Holly NH or some other Model T carburetor because they can be temperamental.

Re: throttle arm to carb Rather than punching out the hole in an intact '27 block, consider installing a gas pedal which is also period correct. Theres not a lot of intact 1927 blocks left. The worst part of a Holley Hotplate carb is the tin heat exchanger INSIDE the unit. They tend to burn through, but we had several that were nothing short of perfect runners.
If the car is a 26 model, theres a chance the throttle rod (hand controller) has 2 holes drill for linkages, but a 1927 only has the upper hole drilled--- another model T anomaly... ws |
Re: throttle arm to carb Thanks for all the input, I am definitely getting an education in Model T engines. After Jack and Steve posted about " vaporizers" , I did a search on vaporizers and learned the difference in carb's. I now believe that the former owner must have switched motors, and installed a 27 engine. There is no pass through for a carb linkage. The pedals are not all the same shape, the brake and clutch look like Model A pedals, which makes me believe that the trans is also 27. The engine number is so faded I can not get a tracing or read it. I also looked at the steering column and the linkage arm is up high to allow the arched wire to cross over the spark plugs and connect to a swivel arm that transitions down to the carb. So I( guess I will have to get used to the fact that my 23 T is more like a 27 T. Dose this mean my engine should be Ford green or black. Thanks for all your help, Ed Saniewski

To help determine the year of the engine, check this dusty 1926. The picture shows the 26-27 wide low and brake pedals, and the two holes on the back of the 26-27 block where transmission braces attach. If it is a 1927 engine, the other pictures of an original cutaway engine in a museum show the colors for it. Two other 26-27 features that may be on your engine would be the fan hub mounted on the water outlet and the coil box mounted on the engine, though it's quite possible to have a 26-27 engine with the earlier coil box and hub setup. The real 26-27 identifying marks for a block are those two holes on the back end.

Re: throttle arm to carb I will check for the holes latter, but I do know that the fan hub is cast into the upper water inlet. The car came with a low radiator, will this be a problem lining up with the 27 engine? Thanks Ed Saniewski

Re: throttle arm to carb I haven't tried it, but I don't think it matters except perhaps for the length of the upper hose.
