Farmall Cub

Yes the carb on the Cub is a Zenith #s 13781 and 10949c-91 or the first # in that sequence maybe a 7. But any way if its right I have to pull the main jet to check the oil and the gas line fitting is to big for the carb.
Please let me know if this is right. THANKS JON

Jon:

really need a pic to tell. From the info you have posted, I am a little confused as may others be as well.

email me a pic, I will post and hopefully this will generate and answer or two that will help you out.
