lenmissy,

Have you checked the carburetor float to make sure it is not leaking and causing a too rich fuel condition?

I've had problems with spark plugs that acted like you describe. I was using the low cost motorcraft plugs. The car was slow to crank and would flood and the sparkplugs would get wet with gas very quickly. After flooding and drying out the plugs a few times it didn't help any more. If it did crank it would back fire and run terrible. This is the way they can act even if the plugs are not very old, after flooding. If you've got any spare plugs it may be worth the trouble to try them. good luck.

Len,

I'm interested in following this tread, but I can't understand what you are saying. Could you please add periods/Capitals/etc. ?

Make sure that the coil polarity is correct. I have a coil polarity tester that really comes in handy. if the coil is reversed it can still run but the spark will be weaker and can cause difficult cranking. Sometimes a jump start with 12 volts will give it the boost that it needs. I am sort of leaning in the direction that bad spark plugs could be the problem. It could still be timing issues. I remember that you said you are cranking with the spark up and that is correct but if the timing is a little retarded you could try advancing the spark a few notches and see if that will help. If the starter kicks, you will know that is not the problem. It could be a valve or valves stuck in the open position and you would lose compression. A good way to check is to place your thumb tightly over the spark plug hole and turn the engine with the starter. When it comes up on compression stroke it will pop your thumb off the hole. Any cylinder that this test fails will likely have a stuck open valve. I can only guess, If you lived nearby, I would help. Good luck.
 
dear len you can type with one finger and still insert punctuation so we can all read your notes a little better if nothing else put a couple of spaces after a sentence so we will know where one sentence stops and another begins thank you very much someone on here can probably help you but it sure is hard to read your postings when you dont use any punctuation your friend freddie

:D

i just experienced a similar thing last night and after checking the timing, swapping out the coil and eventually running the battery down i finally discovered that the throttle screw setting was too low and i needed to pull down on the throttle lever to allow the carbuerator to open up and get some air and fuel through it , usually i did not need to pull the lever down to start it up but i had changed the idle speed recently (and apparently too low)and that was my undoing . basically it only wanted to turn over , chug once than quit , finally after checking everything else i pulled the lever down and hit the starter sure enough it fired right up . hope this helps someone else who may come accross this problem as one more thing to check
 
Are you guys ready rollings sculpt idea was right.Changes coil fires up like a trooper what a hassel now i can play with with my 40 ford thanks guys len
