Tractor wont start hot

[tacticalturnip]

My old Fiat had a problem with hot starting. I think it was solid tappets adjusted too tight. So, a little heat and everything was running loose and it wouldn't start.

I can't say if any modern tractors would have the same problem

Would you say that you had to Fix It Again, Tony?

It was a regular Failure in Italian Automotive Technology.

Three other possibilities, if the fuel pump isn't the issue:

On both my old Mustang and my even older Cub Cadet, the ignition coil would flake out when hot. Some hairline crack in the internal wiring would open up when warm, and then shrink back closed when cold. Very frustrating problem to find, as both would randomly die while in use, and then a little later fire right back up and run fine.

The Kawasaki V-twin on my Deere Ztrak 757 has a habit of boiling fuel in the carb bowl, when shut down after a long mowing session. After refueling and firing it back up, it runs rough for that first half minute, until enough fresh (cool) fuel is swept thru the carb float bowl to get it below the boiling point.

I've had many other small engines, nearly all 2-stroke, with clogged fuel tank vents cause a failure to restart when hot. Always easy to debug by just loosening and retightening the fuel cap, to balance pressure in the tank.

Winter Deere I think his is a diesel

I fixed the problem, turned out to be the fuel pump. Easy fix and she's running great.

Nice you fixed your problem. Why and how does heat affect the fuel pump ?

I'm not sure about that.. I suppose expansion was causing it to get stuck maybe? I also found a few small fuel leaks in the line through this process.

Well, did you also replace the fuel line?

No leaks were at the connection points, and the filter and fixed all that up.

So ran into the problem again today and with what I have learned from the previous process I discovered the solenoid wasn't engaging. I manually engaged it and she started right up.

My Branson 2810 runs great, all the gauges and sensors are appear to work properly, no lights or indicators. However after I run it for about 30 minutes it refuses to start until I let it sit for about 30-40 minutes. When I turn the ignition it just turns over and over with no sign of it even trying to start running.

I thought it could be my temperature sensor because it was faulty. I replaced it however this had no effect aside from making my temperature gauge work again.

Anyone experience this before or have any tips?

Thanks

Check your fuel shutoff solenoid. I bypassed mine with a kill cable
