Hello tractor lovers, i am in need of some more
advice for my old Allis. I have gotten my tractor to
run really good now, but only with the choke all the
way on. I can drive the tractor around fine and it
runs good but i want it to run without the choke on
because i know it's not very great for it. I am open
to anything i have not already tried.
 
i have already done that before i even tried to start it. Then i have done it once more recently. so i don't think it is the tank or fuel lines causing the problem.
 
Go to antiquefarmingdotcom and under literature find the carburetor service manual at the bottom of the page and make sure that you have done everything it says to do.
 
Do you happen to have an in line filter on it??? If you do throw it as far away from your tractor as you can and I bet your problem will go away. If you do not and it is the carb with the non-adjustable main jet did you do as I said and pulled the cap off and made sure you had a good steady flow of gas out of it for say 5 minutes?? Oh and by the way do you have a blue/white spark that jumps a 1/4 inch gap or more. If you do not a weak spark will act like a carb problem because a rich mixture burns easier then a lean one does
 
i made sure i have great spark so there is no problems there. Also what do you mean by an in-line filter? What does it look like.
One more thing, tell me again about making sure i have steady flow of gas. thanks for your tips.
 
There is a plug on the bottom of the carb. Remove it and hold a coffee can under it for about 4 minutes and check the gas flow. You should have a steady flow about the diameter of a pencil. If it flows good for a short time then slows down, start back tracing the flow to the gas tank. If the flow continues, you need to relook at your carb. Bob
