Fuel pump is in back on both of mine. My other one is waiting on parts (throttle cable, hydro filter, seal) before I can try it to see if it does the same thing. I appreciate the ideas and keep them coming. Also, is PartsTree the best place to be shopping for parts?

Best place to start is with the sponsors at the top of the page. :beerchug: I've found cubcadet.com to be more inexpensive than PartsTree when factoring in shipping.

My 2182 hunts also if not at full throttle but I have not run mine with a deck yet.

Parts Tree is a good place to look up parts and if you need anything Kubota go to them on it. I use Messicks and have had great service from them.

I don't have the foam on my hose. On my 2182 it will hunt hot or cold. It's worse when it's cold. I've adjusted the carb also. I also have gauges on it and it never gets over 190 unless the screen is starting to plug.

The simplest and easiest check is the air/fuel ratio. If it is running lean then it will heat up with time. I have a cheap infrared temp gun from Harbor Freight that will tell the temp of any part you aim the laser at. Maybe if you start the tractor and then scan different parts when it is still cool and then as you run it scan the again to see where the heat is and where it begins it might tell you where the heat source is. Running lean is a very common problem and can or cannot have much to do with the cleanliness of the carb. In my case it was particles in the carb but on the Porsche that I used to own, which was air cooled, air/fuel ratio was a must to get right or the engine would self destruct. If you can get an air/fuel ratio meter maybe you can see what you are running. Also the sparkplugs tell a lot about the fuel ratio by their color. Here is a good article on sparkplugs and their color.

good luck.

Guys, the Kubota engine is a really good motor. Made to run under load. It is possible that the jet in the carb is for max load/ fuel. Anything under full load it wants to hunt. That's why it runs fine under load. Because that is where it is getting the best air/fuel mix. Like I stated before, I've worked on these things on several different applications. It's kinda the "nature of the beast". I do think that I got one to stop, but as mentioned, I don't remember how. My memory is so bad I may not even be thinking of a Kubota. It may have been something else entirely. Whichever the case, it doesn't hurt anything for it to be this way. Annoying yes, bad no.

As a note, IIRC, the diesel Kubota's have a buffer spring on the governor. It's job is to take the "bounce" out of the governor. I do not recall if the gas uses it or not and I don't have a gas motor to look at.

I ran it for a while with the side cover off and you can watch the gov try to control it. If you grab ahold of the gov arm you can get the surging to stop. That's why I say it's they way the gov is built. Jon as you say the diesel is stone solid at what ever it's set at.

I really wanted to play with this today but I got busy with my buddy's 1641 get the snow blower off and the deck on (yes July 4th, he has been using a snapper) I did get a chance build a new throttle cable for the other 2182. I got tired on waiting for the $70 throttle cable from PartsTree that I ordered a month ago. Anyway, $8.99 for throttle cable from TSC and a cut off wheel and you'll be all set! I'll hook it up in the morning and run her to see if she does the same thing. But like I said, it only lopes when it's really hot. 80+. Sam, I found the old foam and I'll put that on too to see if that helps with the Vapor Lock situation. I think J-Mech might be right though if all you guys are running these Kubota gas engines with same issue. I'll keep posting my findings if you guys are bored of this yet!

I used my 2182 yesterday for a little while. Paid a little more attention to the surge and I'm wondering if maybe the issue is caused when the carb is transitioning from the slow speed circuit to the high speed circuit. I may play with it some day. :bigthink:

Hey Sam, this is the foam tube I was talking about. Still trying to figure out how to post images.

Anyway, I had other problems with the new 2182 (pictured if it worked) so I didn't get to tinker with the heat issue. Got the throttle cable in, greased everything, changed oil, fired it up and pulled it out of the garage where she idled for maybe a minute, then died.

I struggled with this one. She seemed like she wasn't getting fuel. I could hear the pump running, but still spited and sputtered, but wouldn't stay running. Finally, I took the gas cap off. Tank was completely dry!!!! :bash2: Low fuel light was burnt out in the dash!!!! Check your light bulbs guys!!!!
