I have an Allis Chalmers 314 with the Kohler engine and it starves for gas. The fuel pump was bypassed when I got it so its just gravity feed now. Is the fuel pump necessary? Does the carburetor need some fuel pressure?

 

If it will work fine without the fuel pump I need to take the carburetor apart and clean it I think. How does the throttle linkage disconnect from the top of the carburetor? Its like a ball and socket.

 

Thanks,

Doug

It probably needs the pump. The pump can be rebuilt.  I've seen reasonable priced aftermarket kits for the pumps again but do not know how good they are. The Kohler manual in our Manuals Section can help with the carb removal and rebuild. Good Luck, Rick

You most likely need the pump.

 

Those carbs sort of have a ball joint linkage and there should be a nut on the end you can unscrew to take off the rod and socket.

 

If you can get me the model and spec of the engine I can see if there are any kits available through kohler or an aftermarket source

If its is the style with the spring steel on the socket, you can pop them off with needle nose pliers or a screwdriver.

Its a 14hp Kohler and I think its a K321S engine. Thanks to all of you for the replies.

If it is similar to my 416S tractors, you need at least a half tank of gas to run without the fuel pump.

Thanks Kenny,

 

I did think about that. It actually has less than a half tank so I will fill it tomorrow and see if that helps.

Is the fuel tank screen or nipple obstructed?  Pull the line off and check for flow..

 I just went to the maritimedragracing.com website to list it for the OP. I've had them flagged for years because they made a rebuild kit for Kohler fuel pumps. Well, they have a new website and no longer list the pump kits.

You can always put an electric pump on and it will work fine.

I was short on time yesterday but I did pull the fuel line off above the filter and gas flowed good. But when I took it off below the fuel filter just a tiny trickle. So the filter is clogged for sure. I will get one today and flush the tank before I put it on. Thanks WNYTractorTinkerer for suggesting to check the gas flow. I assumed since the gas filter was full of gas it was good, but I was wrong. I will report back if that fixes the problem. Thanks to all of you for the help with this.

Just for a quick check with the old filter,(if you dont have a good one handy) you can take both hoses loose and back blow the filter with compressed air. That usually blows the crud out and you can test it, but still replace it when you get the time.

I flushed the gas tank, put on another gas filter, and emptied the bowl. It runs pretty well with over a half tank of gas in it. I hooked up the discs behind it and it doesn't stall out under a load like it did before. If you accelerate the throttle quickly from the carburetor it still doesn't take the gas well. So maybe an electric fuel pump would be good. But it is usable now and has a good bit of power it seems.

 

Thanks again to all of you for the input. I have only had this tractor a little while but I can see how these machines could grow on you.

 

Doug
