I put some bad fuel in my 560 back at the end of August. I thought it just had water in it, but it turns out it may also have been growing algae. I drained The fuel system and got rid of all the water, and everything seemed to be fine.
BUT, I was working away from home, and still suspected my farm tank of contamination, so I drove into town and fed the tractor about 20 gallons of un-dyed ULSD. The tractor ran fine the rest of that day, but would not start the next day. I finally got it going by towing it, and baled hay all that afternoon and the next. The tractor sat for two days and then would not start, not even by towing. There was clean fuel all the way to the injection pump, but nothing, neither fuel nor bubbles at the injectors. I was about to give up and get it hauled home, but tried the starter once more, and it fired off.
When I got it home I let it sit for a day, and then it did the same thing, no start, no fuel. I took the cover off the pump, and the shut off cam and the throttle seemed to work correctly. Before I closed it up I poured a little dab of Power Service into the top of the pump and cranked it over, fuel started running out and the stack was smoking, so I buttoned it up and it fired right off. Since then I have found that if I shut it down and then immediately push the shutoff back in, it will start the next morning. If I leave the shutoff pulled out it takes a lot of fooling around, usually towing, to get it to go again. Once it starts and warms up it runs fine and has good power, but the governor also seems a little sluggish, which it wasn't before.
Does any one have any suggestions, besides yank the pump and get it serviced/rebuilt? I am already looking at doing the TA and clutch this winter, and I would try to get by with it, as is, if it isn't going to get worse or give out completely during haying next summer. Should I do the pump first and put off the TA until I get the money? Or close my eyes, grit my teeth, do the TA and hope it keeps running?
