Model T Ford Forum: Forum 2013: Warm starting

Hi,
Can anyone advise me on getting my car to start with a warm engine. I have a 1927 Roadster with a vaporizer carb. It starts fine when cold but is a bear to get going when warm, and yes I do get hot starts with it but if it does not hot start it cranks and cranks...

You have to get used to the car and how to start it. One of mine starts when warm by just hitting the starter or one pull up on the crank. Another of mine needs to be choked even when warm. You just have to experiment until you figure out how your particular car starts.

Hi Randy

As Norm said every T is a little different, but I did have somewhat the same problem.

Try this ..... do not choke, open the throttle several notches more than you do for a cold start. Experiment - it may take 1/2 to 2/3 throttle opening.

If nothing works - check the float level.

Mixture may be too rich when engine is warm.

A richer mixture is sometimes preferred for starting a cold engine and a leaner mixture is sometimes preferred for starting a warm engine.

I goofed. I meant to post this reply here and instead, mistakenly posted it to a thread involving difficult cranking. My bad. Okay, lemme try again:

I used to have this same difficulty with my antique airplane. Now, I know airplanes are not cars, but their engines do work on the same principle. My problem was vapor lock due to heat being trapped inside the engine cowling after the engine was shut down. Without any air flow through the finned cylinders, my air-cooled engine radiated heat like crazy and boiled the fuel sitting in the lines.

In the Model T, which in so many cases has the fuel line running close by and parallel to the very hot exhaust pipe, there is potential for vapor lock to occur, especially when the engine is shut down and fresh, cool fuel stops feeding through the line from the gas tank. I'm wondering whether your problem may be fixed by either re-routing the fuel line outboard of the frame or using some wrap-around insulation.
