F12 needs constant choke

Posted by Wisconsin Erick on June 05, 2007 at 10:26:52 from (75.86.151.61):

Hi, I recently purchased a non-running Farmall F12. It had no gas to the carb so I rebuilt the feul pump. It had no spark so I put a good mag on it. Now it has gas and spark. I cleaned out the carb and replaced the gasket, but I didn't remove it and boil it out.
I got it running last night by pulling it, but it only runs with full choke. Seems to be timed ok because it would fire smoothly. With full choke on, it obviously has no power and starts to die when I drive it.
I tried adjusting carb, but couldn't find a sweet spot.
Do I have poor feul flow? Do I have a vaccum leak?
Anybody run into this before?
Please Help! Erick
