Dificulty starting model A

well and has new spark plugs and new condenser .once it eventualy starts it runs well.

Are you flooding it by choking it when hot starting? Are you retarding it fully? Checked the timing?

What type of points/distributor do you have? If points, what are they set at? Do you have a bright blue spark from the coil when cold? How about when hot, the same intensity?

The carbs are rather basic; mine does that. I retard the timing full, then cheat and give it a slight advance. Throttle to the floor as with any flooded carb, idle mixture 1/4 turn open. It should start if this is the only time you have trouble getting it going. I plan to build a carb myself and see if I can manage to improve this.


Actually, my '77 LTD does that, to a lesser extent, but also carbureted. Starting cold it's fine; if it sits for longer than 20 minutes but less than 2 hours, it's a bit flooded. Carbs are finicky animals.

Lift a spark plugs strap a good quarter inch above a spark plugs then turn over engine, should be a nice hot and regular snap. Point gap that has closed up can make weak hot starting.

Sound like a power valve problem, try replacing it.
