2135 stalling
 

I have a 2135 and it starts fine but then after it heats up for maybe 15 to 30 minutes it stalls. Starts choking and when I look at the fuel filter there is no fuel in it. I let it cool off and it will run for a while and then stall again. Should the fuel filter always have gas visible? The filter is a generic one bought at Home Depot.

I saw another post for a similar problem and suggestions included fuel line from tank, gas cap filter, and fuel pump. There was never an answer to the solution. How do you check these items?

Thanks!

I'd pull the fuel line off at the fuel pump and see if you have a decent flow. Like has been said before we are seeing a lot of fuel lines deteriorating on the inside. I have one in my shop right now that will be getting all new hose from the tank to the carb. Also make sure the heat insulation on the hose is good, if the fuel gets to hot it can boil and cause vapor lock. Check the vent on the gas cap. Check the fuel pump. Check to make sure you don’t have something in the tank blocking the outlet. :beerchug:

Sam Mac,

Thanks for your insight. I think it is the fuel pump. I got a new pump and hoses and am trying to reassemble. All done except putting the linkage from the choke to the air filter plate back on. It is like a jig saw puzzle figuring how to get the linkage together. I am sure it is easy, but I am perplexed! any insight?

Thank you. I always wanted to get one.

I changed the fuel pump and the hoses, except the one from the tank to the filter. I checked the tank air filter and it was clear. It still won't start, but when I spray starter into the carb it starts indicating the spark is good, but then dies. It sounds like it is not getting fuel.

I had replaced the fuel filter previously with a generic one from Home Depot. Should it always be full? It has some gas in it now and before when the engine stalled, it looked like the filter was empty.

Any ideas how to change the line from the tank? Would it be the carb?

I always change the fuel line on tractors of your tractors age, every hose from the tank all the way to the carb. Doubt that the filter is the problem. I also flush out the tank. Pull the seat and fender pan to get at it, also a good time to clean the crud that builds up on the transmission. This is a pic of a 2185 but it's pretty much the same deal on all the 2000 series tractors. Are you sure you put the new pump in correctly? Not sure but I think I recall mention of it being possible to get it wrong on some Kohlers. You may want to post a question in the engine section, we have some very sharp Kohler guys that keep an eye on that area of the forum.

what i have noticed around here is the ethanol is eating the rubber fuel line and the rubber in the fuel pumps......soumds like you got air coming in somewhere.

Thanks to all. More things to check. Could there be a carb problem?

Yep could be but we don't have enough info to know. Try running it with a clean hose to the fuel pump and filter stuck into a jug of gas.

I removed the hose at the carb and turned it over and gas started to pump out so it seems gas is getting to the carb. If it is the carb. is it better to replace it or rebuild. If I rebuild it are there any tricks or words of caution?
