If the air filter isn’t hooked up, you can try temporarily choking it with your hand while the the engine is running and revved up. It’ll suck your hand to the throat and pretty much die, then you pull your hand off quick and she’ll rev back up. Repeat that process a couple times and you may get lucky where she’ll suck the blockage through. Trick I learned from Grandpa to get my B through the day raking hay on a rough field.
If the carbs been apart any time recently, it’s only about a 20 minute job to take it off and spray her out with cleaner without installing a new kit. Seem to have to do one every year in the hayfield on the tailgate of the truck.
Either way a good cleaning is in your future along with probably lining the tank when you get the time.

Ah, I was resizing them on my phone to 2 MB, but not paying attention to the aspect ratio. I'll do better, boss!

A "B" is a great little tractor... Them inline filters are a REAL GOOD IDEA... with or without the sediment bowl..
If your using a computer, open the pictures in PAINT and make them 800 x 600 pixels... if your using a cell phone, e-mail to yourself and resize.

This is my first year having any tractor, period, but I've been pretty impressed. I've been clearing an impenetrable overgrown pasture with 6' high Himalayan Blackberries using the sickle mower. I make high passes and low passes and then drive over it and then do another low pass. It takes time, but it's been working pretty well. It cost as much to rent a dozer for the day ae it did to buy my B. I'm pretty happy.

If I unplug the fuel line at the carburetor, the filter fills up immediately and, at least what I think, is a normal amount of fuel comes out. However, I think it might be worth it to do what you say. Then I won't have to wonder if it's full flow. Check it off.

I'll try the screws and put some thread tape on that fuel port. I'll drain the bowl and tap on it, too. Maybe I'll get lucky. I did rob gas from another old vehicle- it could've had something in its tank or there was something in the bucket. It is possible a jet is clogged. There's an inline paper cartridge filter on it. I always thought those did pretty well. That's all my riding lawnmower has going for it. I did notice while driving that the inline filter is almost empty, but it will fill up after you turn it off. I'm afraid to take it off and not have it run at all without a gasket set. At least now I can move it if I have to. It actually doesn't have a sediment bowl- came that way.

you might pull the plug on the BOTTOM of the bowl and drain the bowl... bang on the bowl to see if you can get any floating crud to drain out.
looks a little wet around the bowl gasket ?? Try snugging the 4 slotted mounting screws on top that hold the bowl on..

running with the choke on shuts of a major amount of air... normally that means your running out of gas... you have to keep the air fuel ratio right to keep it running..
"Normally" the problem is a chunk of crud got in the bowl and is partly plugging the main jet .... a vacuum leak is a possibility , but not as common.
The plug in the front i think is just another location for the fuel inlet if the carb is used in a different application...
You may not need a "rebuild" .. if it runs too bad, you could pull the carb, pull the bowl and blow things out and reinstall....
YES, you can run with the choke on, but you will not have much HP... You need enough choke to keep the air/ fuel ratio right..

Hi all, Me back with yet another annoying question about my B. I was clearing up a storm in my pasture yesterday and then my girl started running like crap and would only run with the choke on full. I noticed some fuel coming out the side of the carb- so I've got myself a vacuum leak. That's my assumption anyway. Pic included, but now I'm wondering if the fuel is coming out of that screw on the end and what that means... I basically have until Thursday of this week to get this done. By the time I order a carb kit and get it rebuilt, it'll be too late. I know running with the choke on wastes fuel, fouls your plugs and valves, and you don't have near the same piwer, but, is it going to ruin anything major? Once I'm done with this, I probably won't need my girl for a month or two- plenty of time to procrastinate on rebuilding the carb/take my time and do it right. I'm debating just finishing, I've got maybe three or four hours of work left. But I don't want to overdo it for my girl and end up with a much more expensive problem later. What do y'all think?
