Morining All,

Im not a very mechanical so Im in need of your help.
have a IH 454 1971 I belive it to be. Recently it
has begun to stall out on me after running about 5 to 10 min. Around Christmas we used it an the amp gauge was all over the place al it quit on us . We put some gas in and fired it up to park it and shut off again. We thought maybe it wasnt getting enough current to run so we decide to replace the alternator. ( asked about this earlier ) Finally got it on due to cold snow time etc, battey kept going dead so we jumped it and she fired up. run it back to the shed in the dry and shut off again.
I let the charger on low all night and she fired up last night but quit again. Any ideas ???????
cant find a fuel filter listing cap and rotor looks good need to find out what distributor is in this tractor . Condenser ??????

Hi, on a gas engine it is either electrical or it is fuel supply. Most stalling problems on 74 series tractors be it Diesel or gas is junk in the bottom of the fuel tank blocking the outlet. Not familiar with the gas engine but there must be somewhere to disconnect the fuel line from the tank by the carb. Hold a clean bucket under it and disconnect fuel line. Gas should flow the full of the fuel line into the bucket. Blowing compressed air back towards the fuel tank will be a short term fix but long term is removing fuel tank outlet out of both sides of the tank and draining and cleaning outlet valve.
My brother had the remains of a dead lady bud in his fuel tank of his 684 causing fuel starvation.

First quick check is the fuel tank filler cap, try loosening the filler cap and running it.

Good luck.

Thanks,
Ill give that a try , Im reluctant to get into too much till i get a good idea of the problem because this has a loader and the supports block the carb and the alternator which I did replace. Thinking about this its been cold since we started having problems could we have water from the ethanol in the fuel icing up ????? Also going to crawl under now its in the dry and see what it looks like under the tank removing looks like a big job!
Thanks

Hi Harry, as I said my experience is with Diesel 454 and 495. I feel your pain with the loader on the 454, there is not much room to work on any of the engine parts. My brother had a 2250 Quick Attach loader on his 495 for a few years. The last 4 cyl gas tractor we had was a 300U with C-175 engine in it and it was cold blooded at -25F, the carb used to frost up and it would spit and sputter and you would have to run with choke part way on until engine got warm and carb stopped icing.
Re gas and ice, I don't know where you live but in Canada it has been common practice by the oil companies to put 10% ethanol in the winter gasoline for several years now. The ethanol combines with the water and eliminated the frozen gas line problem of course unless there is a large amount of water in the tank.

Have you tried using the choke?

Gasoline engines, especially 1960's and 1970's era gasoline engines, are "cold blooded." Until they're warmed up they often need to be choked to varying degrees to keep them running when it's very cold out.

You often need to "blip" or "feather" the choke in response to what the engine needs to stay running. If you don't choke, the engine stalls. If you set the choke and leave it, the engine will flood.

Every tractor's a little different, though. Sometimes you can "set it and forget it" until the engine warms up. Sometimes all it needs is a quick shot. Sometimes you need to put it somewhere 1/2 way and leave it. You have to feel it out.
 
There should be a glass bowl with a screen under the gas tank, also a very fine screen where the inlet line goes into the carb.
 
No need to remove the tank.

Look down the fill cap with a light and you will be able to see if there is debris in the bottom of the tank.

To clean it, remove all of the plugs and fittings from the bottom of the tank,both sides, and remove the sending unit from the right side top of the tank.

Flush with water until all of the debris is out.
Blow out the remaining water, install all the fittings and plugs and fill with gas.

Best done outside where the water mess won't matter.
