Need help - Cub Cadet 1862 dies after running

[Terry Stewart]

I didn't Know that the 1862 did not have the Kohler Command engine. It has the M18,and may have different style carburetor that may not have the shut down solenoid.

Your diagnosis seems to point to a fuel problem and not anything with the ignition. Try running with the gas cap loose in case the cap vent is not working properly. As was mentioned the shutoff solenoid could be a problem or there could be a problem with the pump.

I have a 2284 cub that acted like that. Found the gas line was closing (inside the line, not visible)where it passed through the frame below the seat. It's worth checking, hope it helps. Canhe

I have the 1811 (same engine as yours) and it just got it's second fuel pump a month ago in 22 years. It would run for a bit and then start to sputter and die especially with a low fuel level in the tank, but would run at idle OK.

Took off the walbro carb cleaned and put back together and would run OK for a bit then stall out. I was accustomed to blowing in the fuel tank to prime the pump (made it start faster) so I knew it was fuel related.

It's the M18 Magnum engine 740 hours and since I replaced the fuel pump $55 with a new kohler pump it catches and starts almost immediately - very little choking required. The old pump inlet and outlet valves were tired and the pump bellows was starting to crack .

Its sort of a pain to get at under the shrouding and is about a 2 hour or so job. If this has the original pump I would replace it.

Trying to attack a similar problems with an ATV with hot weather.not knowing your engine, but all suggestions welcome...
Do you have a screen(type filter) in your fuel pump? Is that dirty? Do you have a fuel pump regulator? Or fuel sensor? It looks like the gas is getting blocked, when hot and goes in reverse direction.Any fuel line old or blocked or too close to engine? Any air lines blocked?I pulled of the vapor line of my tank on ATV going to fuel pump and found gas in it on top of fuel pump. Yes, my spark plug looks fine too. Blow your gas cap out and leave it loose running. Did you clean your carb already? Needle getting stuck in all that bad gas? Do you us new gas, octane 91 ( better for got weather) Do you run it with full tank? Another thought...put a teaspoon of Coleman fuel/combustible lamp oil in it. Are your blades running smoothly ( just asking, cause if you had picked up a lot of dirt, engine might get hot too( but on other hand then you wouldn't have the problems you have with fuel). Did you try to just run it on reserve? This might help too. Is your battery cable loose?

Did you find the cause to your cub cadet stalling after a few minutes? Mine is doing the exact same thing as yours. I thought it could be vapor lock, too.

 

[Houkie]

Like Bob mentioned would really try to loosen up the gas tank cap. Vapor lock....( Did previous happen on ATV and weed trimmers).

Here is another problem that I came across in my 2284 CC. After running a short time, it would sputter and then quit. After cooling down, would run, and again quit. It was a bad coil which gives spark to the plug. There is one for each cylinder. My CC has a Kohler twin. Replaced the ciol and no more issues. Just a thought. Canhe.

Here is an update. I went to start it up again after sitting over-night. This time, it turned over and over and over but would not fire. I finally ended up pouring about a half cup of gas into the carb and it sputtered and then started right up and ran. My first thought was did it get so hot that it boiled the fuel out of the carb. So, I pulled off all the shrouds to expose the engine fins. There was some shredded leave debris that had restricted some of the air flow. I cleared everything away from the fins and reassmbled all the shrouds. Started it up and and ran well for about 10 minutes and then started bogging down again under load and eventually died. I did pull both plugs and held them against the outside of the engine and turned it over. It appears I do have spark on both sides. I checked the fuel filter and it appeared to be very dry. I pulled the fuel line off the carb intake and turned it over. It did pulse out fuel so it appears the pump is working. So I removed the air cleaner and proceed to pour some gas into the carb from a small cup I had. As soon as it hit the carb throat it began to bubble and boil. I could hear and see it. I turned it over and it sputtered to life long enough to burn the fuel and then died again. I did loosen the gas cab and actually blew threw the little opening in the gas cap just to make sure there was airflow which there was. So now I am baffled. One guy said the coil might be weak or have a crack in it that heats up and opens up causing me to lose spark. Once cooled down, it would be fine again. Does that sound right? I have not checked the lines coming from the fuel tank to the filter yet so I will do that. When it first died, the fuel fliter did not appear to have any fuel in it however as it cool down, I could see fuel once again partially fillin the filter.

At this point I am open to any and all suggestions so please advise. I did not check compression yet as I do not have a tool to do that but it does NOT blow any blue exhaust. When it does run, it runs fine - no stumbling or hesitation. Any thoughts or guidance would be appreciated. Thanks!

I have a cub cadet 1862 did the same thing. It would run for a few minutes and as soon as I started mowing it would bog down. When I pulled the choke out it would run a few minutes longer and eventually die. The fuel filter had fuel in it even though it wasn't a bunch of fuel there was some. It had me stumped good for a couple weeks. I noticed the fuel lines were really weak and collapsible so I replaced the fuel lines. In doing so as I was trying to drain the tank I noticed the fuel just tricked out from the tank... the shutoffs were full of rust and was not letting gas through so I cleaned them good replaced the bushings that the shut offs go into, all my fuel lines and the fuel filter. My Cub is running great now and mowing great again.

It definitely sounds like a fuel problem and not a bad coil. A bad coil will not keep running when you pour gas in the carb. Checking the fuel hoses was a good suggestion as they get soft with age and collapse. You could jury-rig a piece of new fuel hose and connect to the carb. Stick a small funnel in the other end and pour some gas in the hose. If the engine keeps running as long as there is gas in the hose, you can eliminate everything connected with the engine such as carb, coil, etc. and troubleshoot from the fuel line back to the tank.
