Just acquired a 29 closed cab pickup.
Everything new and/or rebuilt.
Converted to 12 volt.
New Optima battery.
Full tank of gas.
Proper setting of choke rod and timing lever.
Starts very good.
Idles very good.
Problem: After riding 1/8 mile engine dies as if no gas. Will start immediately. Idles very good. Riding next 1/8 mile engine dies again. Repeat starting, idling, dying.
Please help with recommendations.
Thank you.
 
Check the gas cap. It is supposed to be vented. If it is vented make sure the vents are not plugged.

You can use aerosol brake cleaner to help clean the cap vents..
 
Here are a couple pictures of the vents...

I put my gas cap in a jar of gas for an hour and scrubbed it with a tooth brush. All the old crud got dissolved and problem was solved. Wayne
 
If the gas cap is vented take the fuel line off the carb and make sure you have good fuel flow. Also make sure the fuel line is not sticking to far into the carb and the screen in the carb inlet is clean.

Welcome to the club! If anything somehow got into the carb I would take it apart and blow out the jets. It is not that hard to do, takes about ten minutes.

You might also check to see that the fuel line is not too far into the sediment bowl. The gas line should not be more then 1/4 inch past the ferrell on both the carb and the sediment bowl. The fuel flow can be restricted if the gas line is in too far.
 
Good luck with your '29 CCPU. I have one also and my problem was sediment in the gas tank, one of the fuel valve filters fixed that problem 3 years ago, and while I was at it I replaced the filter at the fire wall. Also as stated be careful on how far the lines are into the carb and filter, if they are bottomed out your truck can run just like you described, ask me how i know....
 
If you find it is not the gas problem, check out your coil. I had similar problem and in replacing the coil, it went away.
 
Thank you so much to everyone for your valued tips.
I will follow up with all recommendations.
Will post on the status as soon as I can.
Wife has a list of household chores for me.
But 'a happy wife means a happy life' as someone quoted. :D:D
 
I checked the fuel flow.
Disconnected the fuel line from the carb.
Also checked the filters.
Filters not clogged.
Opened the valve inside the car.
The fuel flow was continuous.
Shook the truck to swish the fuel in the tank.
Kept shaking the truck for 20/25 minutes.
Fuel flow was not interrupted.

Next step is to change the coil as suggested.
Snyder's also suggested to change the condenser.

What else can be the culprit to my dilemma:
Engine rpms consistent, then rpms reduce, then engine dies.
Will start up immediately, then run and die, repeat, repeat.
 
Just happened to think of a way to check your coil and this suggestion is only that. a suggestion. When you start it and at the time it begins to die, stick a screwdriver on one of the spark plugs and ground it to the head. I guessing, but if the coil cut out and caused it to die, then as it is dying, there should be no spark on all plugs. Some of the more experts on this site may say this is a not the way to do it, but from the old guy it is just a thought. I suppose there also could be a number of other reasons why this might happened but it may give you some idea at least as to find out if it is electrical.
 
Did you personally fill the gas tank recently, or was it sitting in the car for a (long?) while...previous owner maybe? Could be gas gone bad? Water in the gas?

Water in the gas is a problem these days, especially due to the ethanol. If your problem is exactly as periodic as you say, its probably not that. But if the interval is a bit more irregular, it may be something to consider.

You can test for water in the gas by draining some out of the tank (at the carb line is good), the more the better. Let is stand for a little while. A clear container is best. Gas and water will separte and be fairly easy to see, especially if you slosh it lightly.
 
Check point gap and colour ..then...

Test the charging rate to the battery.

Could be overcharging and burning the points.
