2182 Question

Jibber · #1 10-30-2016, 11:27 AM

Hi All -

I just replaced all of the fuel lines, fuel filter, and installed a new carb on my 2182. After I did this it would start and run very smoothly. Today is the first day that I used it (under load) to mow and pick up leaves since I did this tune-up. It runs really great and then after a while it starts to struggle and I have to turn off PTO before it dies. It then runs a little rough (surges a little) after I turn PTO off, and then I shut it off. After a few minutes I start it up and it runs good under load for a little while and then starts doing the same thing. I checked the adjustments on carb and they are ok. I also checked the governor and it is adjusted correctly. It doesn't puff black smoke or act like its running rich or getting too much fuel. Its almost like it is not getting enough fuel after a while. The gas light came on the first time it started doing this and I added about 3/4 gallon and seemed to resolve for 10 minutes and then started doing it again but gas light didn't come on so I am sure there is enough fuel. I guess I could try filling it up with gas and see if that affects anything. The engine does not seem abnormally hot or anything either. The engine and radiator screen is free of debris, and the air filter isn't clogged up. My PTO DOES NOT shut off when this occurs, then engine just struggles and about dies. So I am not thinking it is a PTO issue. I then turn off PTO and it struggles a little bit and then I shut it off. Any ideas? Fuel pump? Fill up gas tank? Anything else? After I let it sit a a couple minutes it starts perfect and idles and runs great without load. Thanks for your help!

Sounds like a possible fuel supply issue. Could also be the carb isn't rich enough. Don't tell me it's set where the book says to. Read the book, those settings are only preliminary.

Yes, I think it may be a fuel supply issue. Which one is the pilot screw on the 2182 carb?

There is a screw with a spring around it and then a screw in a similar location as the diagram shows but it is screwed in completely tight and was screwed in tight on my old carb too. If I start to loosen it while running it almost shuts off. So is the pilot screw the screw with spring (Not shown in picture below)? I did adjust that some but ran ok when it was where it first was.

I have a new carb on my 2182 also, and the screw with the spring is very touchy
There is only one adjustment.

So, are you saying that the screw with the spring IS the pilot screw and is the only way to adjust the carb?

I am going to say that the screw with the spring is the pilot screw. The diagram in the manual is not an accurate description of what the carb actually looks like. I fired up my 2182 this morning and ran it for 10 minutes with no issues. I adjusted the screw with the spring some and it definitely affects the performance. After warming it up I set the engine to idle. I then messed with the pilot screw some. I wanted to make it a tad richer. I went too rich at first and when I would give it full throttle kinda fast the engine would hesitate a tad. I then turned the pilot screw in to make it more lean until the engine would throttle up with no hesitation. While running the 2182 for a few minutes the fuel light came on again. Am going to add some more gas today and see if the initial symptoms weren't caused by not enough fuel in tank.

The issues started when I was mowing and turning alot. The little bit of gas could have been swishing around and not getting sucked in by the fuel pump. Also, when I let it set for a few minutes it would run good again.

Step 1: Add more gas!

Yes. Maybe the float level can be adjusted but that's all I think

Learning from what I've read here, I replaced everything that had to do with getting
the fuel to the carb. Lines and filters shutoff valves,pump,etc. I'm not one for messing around with old fuel related items.

Just as guess. When it stalls, quickly pull the incoming fuel line off the fuel pump and see if you get a good stream of fuel flow by gravity.

Or you could pull the pressure side hose off and see if the pump will spit fuel by using another hose to divert fuel away from the hot engine.

you make no mention of cleaning the tank shutoffs,did you clean them?

Dirty Steve · #10 10-30-2016, 06:57 PM

Your other post mentioned cleaning the tank. Did you pull it out? Master Lew has a valid point about the tank shut off valves. Clean or replace the shut off valves. All new rubber grommets for the shut offs and tank fuel gauge..... if you have not done so already.
