I own an older Kubota B21 TLB that has a tendency to randomly stall or lose power without notice. If left to sit for a while it will usually start and run fine until the next time. I think it is a fuel related issue but I would appreciate any ideas.
Check/clear fuel cap vent.I own an older Kubota B21 TLB that has a tendency to randomly stall or lose power without notice. If left to sit for a while it will usually start and run fine until the next time. I think it is a fuel related issue but I would appreciate any ideas.
It bogs down and looses power until stalling.The other option would be a failing stop/run solenoid, or safety switch controlling it.
Does it bog down or just shut off?
Any smoke before or after?
Thanks for your ideas I will check it out and report.Both those things point to a fuel delivery issue.
I would go through every part of the system and see if there is any flow issues.
The B21is still stalling, just stops running. There is normally a single clicking sound like a relay or switch when the key is turned to the warm position, after it stalls there is no click so when the key is turned to start and it will crank but doesn't start.Bet you are correct - fuel related.
Empty tank - change filter(s)- check air filter -open throttle - bleed lines - report back
Sounds like the fuel solenoid North Idaho Wolfman mentioned in post 5. You could temporarily wire a 12v bulb in parallel with it to determine if power to the solenoid is intermittent.The B21is still stalling, just stops running.

It seems like an electrical issue.
