Model T Ford Forum: Forum 2015: Starting question 1927 coupe(NOT AGAIN!)

Still trying to get this 27 engine to run. Got the rebuilt carb from Lang's today and that solved the gas problem flowing out. I was able to get the engine to fire but unable to keep it running for more that several seconds. It finally fired and ran on 1/2 choke for about 15 seconds then backfired through the muffler and died. Any and all suggestions will be greatly appreciated. The engine hasn't been started in at least 20 years. Could the timing still be off or are the valves stuck? I did remove the side cover and squirt MMO on the valve stems. Harv.

Did you drain all old fuel from the tank and fill it with fresh gas?

When you had the valve cover off did you slowly hand crank the engine (key off) and notice if all the valves moved up and down?
If you got it to running and the valves aren't stuck it sounds like it may be a fuel mixture problem.
Did you adjust the carb? The usual setting to just get it to start is somewhere around 1 1/2 turns out.

I did check the valves when I had the cover off, they all seemed to be moving ok. I did not adjust the carb that could be the problem. the short time it ran it smoked slightly but seemed to run fairly smooth. I'll tinker with it again tomorrow. Thanks for the suggestions. Harv

I have put these things in possible order of likelyhood. So do one step at a time until you fix the problem.

Every carburetor must be fine tuned. Depending on the temperature it might need to be richer to keep running when cold. In warm weather you might not need to adjust it at all. Try opening the needle 1/4 turn and try again.

Also, the fuel tank might have a lot of sediment in it and the fuel feeds from the bottom of the tank. You need to start with a clean tank and clean sediment bulb.

Also depending on where you are located and the humidity, you could have condensation in the gas tank which will also settle to the bottom. Drain some gas from the sediment bulb and see if it contains water.

Don't give up. Eventually you will get it to run.
Norm

about 1 second of choke is all any of my cars will take. did it really need to be choked 15 seconds to stay running, or was 15 too much? will gas flow out the line steady when disconnected?

Harvey,

To add to what Norman said, when he said to open the needle valve 1/4 turn, he meant in addition to what it is already opened to. Not 1/4 turn total.
Try that, if it is a little better but still not great, open another 1/4 turn.

Or, close the needle valve completely and open it 1.5 turns. This should give you plenty of mixture to get the car started. Assuming it starts & runs, you'll soon find that this setting is a bit too rich. Slowly turn the needle clockwise to lean it out until the engine runs well. If it begins to slow down, open the needle up again until it gains speed and evens out.

Thanks to all. I will do the carb adjustment tomorrow and let you all know. I hope that is the only problem. It did run fairly strong for about 15 seconds but only with the choke 1/2 closed. Harv.

Harvey: The PM that I sent yesterday, did you understand any of it? I hope so and maybe some of it may have helped. Just curious.

HAPPY "T"ing When it does run it will be fun to drive and an eye catcher

Bill, thanks for the PM. I did understand it and am on my way out to the garage to try my luck once again. Got side tracked this morning hunting a very sneaky coyote helping himself to the neighbors chickens. I'll post if I get the engine started. Thanks again. Harv

I don't mean to give all who responded to my starting question a swelled head, but thanks to all the master T mechanical, information filled, and down right smart people I got the T engine running. I printed out the forum and made virtually all tests, inspections and adjustments suggested by all and the engine fired up and runs beautifully. This site is wonderful and an essential resource for anybody with a T, and in my case after a 40 year absence from the hobby I have forgotten everything I once knew, and probably didn't know that much to begin with. A hearty thanks to all. Harv.

Harvey I was wondering about the rebuilt carb you got from Langs. Was there any information in the box about it such as carb. adjustment or set up?

Glad you got your T running. Sometimes suppliers will have a info. sheet with their rebuilt product.

I haven't bought any rebuilt carbs so that's why I was asking.

John, no instructions at all, But a very nice looking and apparently functioning carburetor. Had instructions been included I would have known to adjust the needle in and then back off 1 1/2 turns. Thanks to you and all others who responded the instructions were not needed.Harv

Harvey that sounds good. I guess the rebuilders expect a buyer to know what to do. I would think for what you paid for a nice rebuilt carb it should have been adjusted to the initial start up adjustment or have a adjustment info sheet with it.
I always have to refer back to the Ford service manual from time to time when I work on my car and the different adjustments it might need.

I have one next to my 'main chair' in our den in our book rack to refer to just to refresh my memory!!

Harvey: Well of all the help it is going to be hard to decide which one was the one that put you over the hill. Great. Glad to hear it worked.

Bill, I think it was a combination of all who responded, and beyond that just the response my question generated gave me hope to keep trying. It paid off. Harv.
