Hard to start

Engine turns over normally but when I PULL the choke out,momentarily, the engine STALLS but SLOWLY continues to turn then FIRES and runs. I have a 6volt battery and did a load test on it and it tested fine. I also did a vacuum test and all indicates normal. I have the same starting problem when the engine is warm on a restart. Could this be a starter problem? Can I test the starter with out removing it from the engine?
 
Sounds like too much advance on start up. Do you have the spark control all the way up when cranking.
 
I forgot to mention I have a B engine with B distributor and B carb. I was thinking about changing the distributor back to a stock A and see if that changes my problem.
 
You might check your static timing and see if it is close to O* or at TDC. If it is advance more that a few degrees you may get kick back. That is the slowing of the starter you are hearing.
 
I'm not sure what you mean by 'stalls'. Was the engine running, then shuts down and restarts ? Or does it just slow down or spin slower while cranking ?

The Model B initial timing is 9º advanced over the Model A. Retarding it a few degrees may help.

You can also check the draw on the starter motor while cranking [ignition off], that will give an indication of the health of the starter.
 
Well I feel foolish. Months ago I installed a rebuilt B distributor. Lately I’ve been having a momentary miss, when starting out from a stop. I checked the point gap and sure enough there was very little so I adjusted the point gap and no more miss. Well I forgot my advice to club members that point gap AFECTS TIMING... DUH! Soooo I adjusted the timing and NO MORE STALL while starting. My THANKS to all who set me straight. 👍 😊

A good way to check and see if TOO advanced initial timing kick back is the problem . turn the ignition switch OFF and try the starter . If the starter doesn't try to buck and kick back and spins as normal with the switch off ,The timing is the problem . Another thing to consider is that the spark should ALLWAYS be fully retarded when starting the engine .
