1953 jubilee

[Anonymous-0]

Hey all i have a 1953 ford jubilee, Just today it will start up and idle fine and i can rev it up and it runs fine, after a minute or so of driving in any gear underload it will begin to stutter and then die. but then ill start it right back up and it will run a bit and then stutter and die. as far as i can tell its getting plenty of gas, i checked this by taking the bottom nut out of the carb and a steady stream of gas comes out. Its getting good spark, has a strong battery. any ideas thanx! i ran this tractor all winter long without any problems...

Is it floodin'. As if a float problem. Also, have you changed plugs in a while. Make sure she's wired up right. Also is the coil gettn too hot? If your driving and bouncin' might be a sign of loose wire somewhere. Also, if that gas is from the winter, that cant be good. Just some suggestions.

sparkies are nice and clean, and ill have to check the coil tom... all the wiring looks good but ill check it... Would a stuck float, allow the tractor to run for a while just fine and then not? and what would be a quick fix or test for a stuck float... also if i leave my sediment bowl on for a few minutes without the tractor running and then undo the bottom bolt on the carb a LOT!!! of gas comes spewing out the bottom... and then returns to the normal stream.. Is this normal??

well if your are not having any problem getting the gas "to" the carb, maybe your problem is getting gas "through" the carb. That probably makes more since since it runs good without a load but as soon as the engine wants more gas it starves it out. One way you could tell, when it starts to die out, pull the choke and see if that keeps her runnin'.

well pulling the choke does make a difference but certainly doesnt fix it it will then run a little bit longer and then sputter and die... so i agree it must not be geting gas through the carb. so now what?

 

[Andy Borden]

From what Ive read here on this site, Rebuild her or tear it down and use some carb cleaner and use compressed air a blow every nook and cranny in order to get the gunk out. I had the same issues but my problem was a dirty tank. I pulled the tank and no lie, I got a coffe cup full of crap out of it. If you rebuild it there are some very reasonable kits out there. But I'd try to clean it first. I just had mine rebuilt and bought a kit that had every possible piece with it to change out. I know I asked you this earlier but are you running old gas?

Alright ill try my carb cleaner and bang around on it with a hammer a little bit and see what happens haha... and im running good clean gas

almost certaintly sounds like fuel delivery.

pull the plug on the carb again and let it drain into a jar.. it must maintain a stream.. many times people pull the plug.. let 2-3 oz drain out and figure flow is good.. but all they have done is drain the bowl.

post back.

If pulling the choke out helps, then it is probably a fuel problem in that the supply cannot keep up with the demand. Based on what you have said, check the gas cap. It is supposed to be vented. The vent may be clogged. You can blow it out, and or start up the tractor without the cap and see how it runs.

When you pull the plug on the bottom of the bowl let it run into a container for at least five minutes, watching the flow. If it is a good steady flow, then the problem may be ahead of the carb. There is or should be a screen in the sediment bowl so check it. There is also a screen inside the tank attached to the fuel shut off valve that sometimes plugs as the tractor moves stirring up sediment that clogs the filter. Remove the cap and look inside with a flashlight. If everything checks out, then its time to clean and rebuild the carb. Make sure you disassemble the carb and soak over night in a good carb cleaner, then scrub, chase the passages with a small wire (not too big) and blow out with compressed air. Napa sells a gallon can for cleaning carbs. It has a parts basket and the cleaner is reusable. When setting the float, make sure you take the measurement with the gasket in place.

As for "a lot" of gas coming out when the bottom plug is pulled, it is simply the bowl emptying itself and then the stream created by the open float. Hope this helps.

Dont they all seem to run just fine before you park them for a while. I would definetly think it is a fuel flow problem somewhere. Maybe one of the Tractor Guru(s) will pick up on this one and add a little more insight. Hope you get it all worked out. Post back.

If you tractor has a metal fuel line then disregard this, but if it has a rubber-type hose feeding fuel to your carb check the inside of the line. The ethanol will dissolve/degrade older fuel lines and they can collapse the lining inside the fuel line. And always always always USE STARTRON fuel treatment, especially in your two cycle equipment and anything that sits for more than a week.

I have used ethanol blend in every thing I own including ,lawn mower, chain saw ,and weed trimmer for 10 years .In fact I have been running E-85 in a 641 for two years. Still waiting for somthing strange to happen. By the way, youngn, why don't you try replacing the condenser.It fixed your discribed problem, I had.

It sounds like it could be the wire mesh filter on top of the fuel cut off valve is sucking up dirt or rust and plugging up

You can remove the gas line from the carburetor, and with the fuel shutoff valve on the bottom of your gas tank open and gas cap off blow back thru the line cleaning the screen in the tank.
Make sure you have the gas cap off the tank and the valve open or you may rupture the tank.
I have used compressed air to clean the screen in the tank but be careful so you know what your doing!

There is a screen on the fitting that connects the gas line to the carb. I had similar problem, tractor runs fine and then dies like it ran out of gas. When you drain your carb use a white paper towel and look for crud in the gas. My crud got past all the screens and bowl. I cut my gas line and and added an in line filter and it solved my problem.
