53 Golden Jubilee stalling

[Gord C]

I have a problem with my tractor stalling out. what I have noticed so far is that it starts up great, runs good about 5-8 min and the all of a sudden stalls like someone threw a switch or it ran out of fuel. It restarts right away ( choke has to be out)an it idles normal but will stall as soon as clutch is let out( Engine is warmed up to temp.) I can keep it running for a while, poorly thou & lacking power,if I throttle up or pull the choke out. To me I thought it was lacking gas but fuel sediment bowl looks full when it stalls out. I drained carb thru screw in the bottom of it and fuel came out looking clean thinking it may have somthing in it and it gets sucked up and then stalls. It did this about 2 weeks ago then it cleared up and now it has started doing it again.
Can anyone help me with this, driveway is full of snow again and i need to plow it so i can get out :-(

Fuel
3-8 min just happens to be how long it will run with a plugged fuel line. Usually dirt in the screen at the elbow where the line enters the carb.

Thanks, i will check that out, the dirt obviously lets go and travels back up the line ?
and thats what allows it to restart?

I'm guessing partially obstructed fuel line.... after she stalls, the fuel bowl takes a few seconds and fills back up thru the slow obstruction.

Probably doesn't go back up the line but floats back to the bottom of the elbow then the gas flow pulls it back to plug the screen when you start the tractor.
Good Luck, Lee

As the others have said, sounds like a fuel restriction, however the lack of power may be due to misconnected spark plug wires. The firing order is 1,2,4,3 CW in the Jubilee engine. Also be sure your air cleaner is not restricting the air flow to the carb.

You might want to check the spark when it dies on you. I had a a similar failure with my TO-30 suddenly stopping while I was plowing snow. I checked the spark at once and it was there, but not a real FAT and BLUISHh-WHITE. Tried a restart and it ran well the rest of the day. Today as I was plowing snow it happened again. Again I checked the spark, fine. Started up and ran for 10 secomds and died. I checked the fuel thinking maybe some condensation got in to the fuel bowl so I ran some fuel out of the bowl. Tried a restart and no deal. Checked the spark and no spark. I have a Pertronicx and I thought it may have failed but I got a jumper and put it across the key switch and it started right up. I finished the plowing and drove home and posted a message to Dell about the specifics of his marine ignition switch since that"s what I"ll replace my switch with. this wasn"t the classical run 10 minutes and dies scenario that I had heard about regarding kew switch failures. By all means check out the fuel system but don"t ignore the ignition system because it is the source of the vast majority of these types of failures.
Hope this helps you.

Hi, its me again,
Been out farting around with this, Think problem is originating from sediment bowl/bottom of fuel tank. after i have taken off the Bowl and went to screw it back on and before the bowl totally filled up i could see the stream of fuel slow down and almost stop the tighter i screwed the bowl on the slower the fuel runs.
How does the bowl & assembly attatch to the tank? and how does that assy work?
Thanks Gord

The fuel bowl screws up into the gas tank. What you saw was a normal condition. When the carb bowl fills with gasoline, the float in the carb shuts off the gas flow. No more fuel will enter into the sediment bowl until gas is drained from the carb. You can totally fill the sediment bowl by loosening the retaining nut on the bottom of the sediment bowl allowing air to escape the bowl allowing more gas to enter.

As the carb bowl fills, the flow of fuel will stop due to the float valve.
