John Deere B Carb/Governor

You may have a fair chance of recovery without pulling the carb. From the URL below, you have what Robert Beaver once stated was 90% of all carb IDLE problems -- three segments of the IDLE passageway, and at the very bottom is segment # 3, also known widely as the SECRET PASSAGE. Robert shows use of a No. 53 Drill bit (0.0595-inch diameter) to clear the way. Getting the drill plug out stands in front of trying to see to it that the way is open. Now, if Burrey was indeed in there and opened it up, getting the drill plug out shouldn't be hard. And as pointed out within this thread, dirt particles have been known to become lodged -- closing the hole back up again!

And if this don't get you home, then yes -- the carb needs to come off and at minimum, these three segments must be cleared. I wish you well -- (PatB)

Also � It wouldn�t hurt to run a quick test on that carburetor. Again, scan across to ARTICLES 1, and from the drop-downs, select CARBURETORS. And, also � at the very end � is a no-wrench test of the two pathways of your carburetor, IDLE and LOAD.

Now � hard to start normally but will start by pulling points directly at the ignition system � do you have magneto or a coil-based ignition system? If magneto, is the impulse clicking nice and crisp or sort of a dull thud � or no click at all! I hate to go on & on here � not knowing your ignition system, but if your tractor has magneto, go back to the �H� site, scan across to ARTICLES 1, and from the drop-downs, select ELECT SYSTEMS for a good read on magnetos and troubleshooting them.

You indicated plenty of fuel seemed available and so I won�t go there for now. But one last read over at the �H� site you may find helpful is under ARTICLES 2, called LOSS OF POWER. This short piece kind of sorts things out � in detail for the �H� tractor, and much of it will apply to your �B� also. (PatB)

I have also had some issues with carbs. from that place in the past. The tiny brass plugs were not sealed and sucked in air makeing it impossible to get adjusted right.

Check your throttle linkage and make sure it is the correct length. Set your throttle to full, then set your governor throttle plate to full open, set your linkage to be 1/2 the width of the hole just short of making it to the hole. Once the length is set then you should have to pull against the governor spring to get the linkage in the hole. Do a search and you will find many posts on this topic. Have you checked all of the other obvious and not so obvious items?
