Need help getting a Motorcraft 4300 to run.

Still no Joy eh Pepsi? Did you replace the float? Sometimes they get a hole in them or the foam goes bad and absorbs fuel. I would keep this carb and buy another one for the time being.

yea replacing the float is probably my best bet but the friggen thing alone is around 100$. so im bidding my time hopping that someone in my area decide to get rid of a there 4300 on the cheap so i can go steal there float but so far no luck. and yea still haven't had a good ride in it this year but i still have 2 months of summer ahead of me so im still hopeful.

The float should feel light as a feather. If not it is bad.

it is fairly light and i tried submerging in a gas can and nothing got into it. i will say tough the material the float is made out of feels soft, i am pretty sure that i could make a hole in it with my finger nail. i guess the material itself absorbed some gas and got heavier trough the years. argg im probably gonna give myself a kick in the butt and splurge on a brand new float.

Sounds like you have the foam type. They do go bad.

so i finally got fed up after opening the carb another dozen time and bought a new float! received it today. it is now installed and the carburetor no longer fload itself! but the car still wont start realised that i have very weak spark at the spark plugs so onto the next problem!
