New discovery on cold start

[Trkrd]

I've been having a hard time (to say the least ) getting my 240D to start on the recent cold mornings. Then after some reading here and poking around under the hood I foud the "TS". Put a little fuel in the bowl, tried again and...nothing. After checking all connections, found the outer nut on the outside of the electrical connection was loose. After tightening this up it starts like a charm without even using the TS, even at 28 degrees! Thought I had a major priblem but was as simple as cranking down a connection. Just thought I'd share this with you guys and new owners getting to know their tractors like I am.

I'm confused by your post. I have a ym2000 which is the grey counterpart to the 240 and has the same thermostart system. I understand you put fuel in the bowl and tightened a connection and now you say it works WITHOUT using the TS. Not sure I understand how that possible. The TS doesnt work without turning the key to the "ts" position. So how can it have helped if you are not using it???

I originally found the loose fitting when I put diesel in the TS reservoir for the first time. Turned the key to the TS position and saw smoke coming out of the fitting. I probably should not have said "loose" , it just needed to be snugged up a bit. After the first try, and seeing the smoke coming out of the fitting and fuel leaking from it I have not put any fuel in the cup and it remains empty. Since the fix, the reservoir has been empty and I have no problem starting it without fuel in the TS reservoir.

The later ignition switch heats the TS element when twisted to 'Start' as well as when twisted left.

The fuel in the bottle lasts a long time, many starts. Could there still be some in there?

It all leaked out. And afetr tightening the fitting I found the hose to be dry rotted and leaky. Haven't made it into town yet to get a new hose so I'm sure there is no fuel present. I'm thinking that maybe the electrical connection was affected by the loose fitting and therefor not heating the TS. When I was having the trouble with cold starts (before I knew about the resorvoir ect.) I always held the key to the TS position for 15 seconds and nothing. After I messed with it and put fuel in the cup, I would hear the snap, crackle,pop going on in the manifold and it started right up. No problems since. Actually , the sound of a forrest fire coming out of the breather was a little creepy. Maybe I'll leave that little fuel cup alone!

By the way, Now that I'm pretty much done tinkering with it and getting to know my way around it, I've put it to work. This little booger has some serious POWER! Feels like a full sized tractor condensed into a compact. I'm amazed at the capabilities of this little guy.

My TS. has been off for Yrs. and since the New to me has worn off, I'm not going out on it anyways ESP if it's that cold 40's Maybe. Or I'm hiding from the Wifey

 

[Trkrd]

Yes, the tractor will go places the wifey won't 4WD makes hiding a cinch!

Bah. Who needs 4wd.

I made this picture last weekend to share with a friend, and I'll share it here too. I have just removed a stump and I'm starting to scoop dirt back in the hole.

This was intermittent rain and the ground was muck. And the firm parts were so slippery I had trouble walking without falling down. I pushed into a full bucket of muck and when I went to raise it all that did was bury the front tires in the stuff so each was in its own 16 inch cavity.

I got off to see what was the matter. Turned out the backhoe bucket had gone aground and was partly supporting the back of the tractor. No wonder it was just sitting there digging cavities under the rear tires. I raised and extended the hoe to unload weight off the front (like a cat or squirrrel uses its tail). I also dumped the front bucket, then used it as a toboggan to lift the front axle and tires out of the muck.

Then backed right out.



Actually today finishing filling the hole was harder. I arranged the work so I drove uphill into the mess then backed down back-dragging the surface level. But with the back tires over the stump hole, on top of 2-3 ft of muck, I had to use the bucket curl to help it back down the grade a couple of times.

I never have stuck this thing but I have used the bucket curl to get it moving a few times.

I wish I had 4wd because that will pull the nose into a sharp turn better than using individual rear brakes. Aside from that, with this backhoe I can load nearly 100% on the (oversize) rear tires so this is a pretty good mudder.

They used these things in rice paddys, after all!

Are you sure about that, Cal? I have a new switch in my YM2000B, and to my knowledge, it only heats the TS element in the TS position. I won't see the tractor til May, but will have to check that out. I would imagine just heating the element, without fuel, would assist some in starting.

I've never had to fill the reservoir, one morning last week the temp. had got down to 27* and I wanted to find out how the tractor would start cold not being started in several days? It did as always, turn the switch to on position for approx 10 sec. it then started up right away as usual, I've not owned but 2 tractors and this one definitely starts up quicker than the first one I had owned, the Old Kubota had the kind of switch you turn back and hold for about 10 sec. to heat the Glow plug it would always need 2 -3 tries before ever starting, actually I would run the battery dead some times while trying to start it in cold weather, one time I tried the Ol- starting fluid trick and would start it right away. was better than going for the battery charger each time .. Note:... but the use of starting fluid is a Bad idea, it became addicted to having to use it and 50% of the time I would need it to crank the old boy, I never would use this again on any other tractor, I was lucky not to have blown the piston out of the engine, I think back because of this tractor being low in compression and only being a 1 cylinder must have help it to survive this stuff,

I've I only had my Yanmar since July and not really had the opportunity to do much with it, But from what use I have had,it is a mighty little tractor,
