1982 Bobcat 642 with Ford engine and Zenith carburetor question

[Jskosk]

Newbie here, have pretty good mechanical background. First Bobcat (1982 642 w/ Ford 1.6L) I've ever owned, picked it up from a farmer in Northern Illinois with approximately 3300 hrs. Have owned it about a year was always hard starting after new fuel lines new fuel pump (electric) I found out the starter was shot. Had it rebuilt and the machine has never run better until a couple of weeks ago. First carburetor problem was fuel running out the intake throat, was able to resolve that without taking carburetor off thanks to Youtube Moyer Marine tips. But now I was using it the other day and had been using it for about an hour when it just shut down like it ran out of fuel. Fuel 3/4 tank fresh gas. Checked and tested ignition system OK, and fuel getting to carb. Checked/tested fuel shut off solenoid OK. Can spray gas into carb and machine will run. I need to remove carb. Does anyone have any tips/ procedure for removing that carburetor. It crosses over to a Zenith 13805. It looks like a bear to get to to remove. Any help / advice would be appreciated. Thanks

The biggest obstacle in your way will be the governor and the belt guard if you still have it. Once you pull the belt guard off access is actually very reasonable. That carb is actually pretty easy to remove all things considered, just pop the air intake hose off, the throttle and choke linkages, then there's 2 bolts that hold it on, one short one and one long one that goes through all the way to the top of the intake manifold, once those are off you can sneak it right out of there.
If it just suddenly stopped running it could very well be the anti-dieseling solenoid if your carb still has it, it's on the back side of the carb. Lots of times people just take these out and put a plug in its place. One of my machines has one, the other doesn't and the one without will diesel a little bit after shutdown if it's running lower octane fuel, I find running a high octane fuel cures that problem. Hope this helps!
