430 case running bad

[Fred Hart]

my friends 1964 430 gas case tractor is running very bad, will only run if you pull out the choke.

does that mean the carb is stopped up.

any ideas before i take a look at it for him.

will drain the carb and gas tank, change fuel filter and add new gas.

thanks,

Mine was like that. After cleaning tank, lines filter & putting a kit in carb, it still needed half choke. I removed the carb several times & finally gave up. Took it to a friend who eventually removed a seat just below the high speed needle valve. He put a different needle valve & it ran like a new one. Can not explain why it didn't like the seat.

Make sure the new filter you use is for gravity flow fuel systems. Current automotive fuel filters are for pressurized systems and will impede flow in gravity systems like antique tractors.
