Thanks guy's for the help on finding my starting problem. Now it starts but when if gets warmed up it will not start again. Any clues?? Rebuilt the dist, coil is good and so is the cable, they show good on the meter. Thanks

Does it spin over when hot, or not crank at all?

If it turns over, hold the coil wire 1/4" from a head nut to see if you have a good blue spark.

Hopefully you aren't pulling the choke once the engine is warmed up.

Running to rich and fouling the plugs?

If the btiming is set a little too advanced, the starter will kick and act like the battery is low and it won't crank, just a guess.

Many times a hot engine on restart will start easier if you open the throttle slightly just like on a cold start.

1. Pull the throttle lever on the column down 3-4 notches.

2. Then look at the carburetor to be sure the linkage is actually opening the throttle lever on the carb. (10 degrees or so).

Every linkage is adjusted differently and opens different amounts.

3. Try to start ... If engine runs very fast when it starts, use less throttle on the next restart.

Some carbs start fine from an idle throttle position without doing this. While other carbs need this extra procedure.

Tried the carb. throttle, no work. Never had this problem before. This is a new rebuilt engine from last year. It ran great all last summer, put away for the winter and when I started it up 2 weeks ago it started and ran great, After it was good and warm I stopped the motor and later that day went to take it for a run and that's when the problem of starting begun. I have metered all the electrical parts and replaced some, rebuilt the dist. Am running 12 volt system. Can not find any mouse damage in the wires. Now I am lost!!!! Thanks Tom

Are you using the choke on starting after it is warm?

Condenser?? Point gap?? What do the plugs look like??

It sounds like you know what is what, but sometimes it is just the obvious.
If the engine has sat longer than an hour or so after being warmed, it will require choke. If it is still warm/ just ran, like others say, give it a few clicks on the throttle lever & if choke has been leaned off, give the knob at least quarter open. Other than something silly like that, it may be electrical.

The easiest thing to do is try the choke. It may need just a bit of choke, not much. Pull the choke on for maybe 1/2 a turn and push it back in. It should start right up. Mine is old and tired and I have to strangle it to get it going if it has set for for any time. If not, then maybe its electrical. Try for a spark from the coil wire like Tom suggests. If no spark, it seems like it would be a faulty condenser, or, possibly a coil [doubtful, but, possible],or, a bad primary ground.

Have you checked the polarity from the coil to the distributor? I have encountered several Model A's with the polarity reversed which affects starting when hot. The vendors sell a led device which indicates polarity direction.
