I'm repairing a 1993 2510 Mule that's sat for a while & had people working on it that shouldn't have.
The current issue is a long slender spring that was bent and mutilated.
I've managed to remount it but it's not right, it's too short and under too much tension, so the engine isn't happy.
The Kawasaki part number(s) are 92144-1723, another is 92144b (drawing number?)
All the info I can find on this says that it's obsolete/out of production, does anyone know if another Mfgr produces a spring that can substitute?
Thanks.

If you add a piece onto the existing Spring, 1st make a tiny loop so when it pulls, it will hold, do that to both ends, then you could solder the two pieces together and get it to work. I've done this on a lot of lawn engines that have that same long spring set up. Kind of a hack, but works. The other way is to go to a really good hardware store, the really old kind, and search their spring inventory, I have found springs like that, sometimes too long, which is better than too short. A Kawasaki dealer may have something like that sitting around, especially an older one.

Rubber band works in a pinch .... it's just to keep the throttle and govonor rod tight ....

I think so, I checked the inventory on that site just now to make sure & like the others, sold out/not available.

Ya, this reminds me of the work I did 40+ years ago on my model airplanes, thanks for shaking up the old memory cells!
We still have a store like that in town, used to have one in Ottawa as well, Pascal's Hardware. They were my go-to guys back in the day....

There is one other option that is a lot simpler than calling every dealer in Canada or the US hoping that someone has it in stock. If you go see your local Kawasaki dealer, he can put your part number into Kawasaki Corporate for a dealer by dealer search.

Check out this link. Scroll down to the bottom. I think if you look by measurement, you should be able to find something.

Yeah thanks, I've been looking at similar items online, the problem is that I've gotta check with the owner before spending money. We're just trying to get it running for resale so he's not eager to open the old wallet,lol

 

[Kawasakian]

If he's that cheap, then uncoil the spring with some needle nose pliers till it's long enough, and you will get it working.

Wow he is getting you to do all the work and he is too cheap to buy a spring? He must be a good friend because if someone did that to me, his Mule would be rolled out my door pretty darned quick.

 

[Howardtheduck]

He's a good guy I guess, only that we are just starting out doing this together and he's not sure of my skill level.He's putting all the cash up front and we split the profit once we sell. After a couple of successful deals he should trust my diagnostic abilities. Or else, "Here's your hat what's your hurry"

I got it to start/run reliably today. I McGyvered the spring using Kawasakian's suggestion.Thanks.
The only issue is to get it to idle slow enough to shift cleanly, too much grinding still.
I don't have a tach but I figure it will go as low as 1100/1200 rpm before it dies, the needle valve for the idle air bleed is Fubar'd/scored, doesn't do a blessed thing to adjust the mixture.
Maybe time for a China carb?

 

[Howardtheduck]

I adjusted the valves as well. The back cylinder was bang on, the front was a bit loose.

Sometimes you need to add a return spring on idle end ..to bring it to the stop ... They have a governed idle ....

I believe it's hitting the stop properly,the engine just isn't happy at lower rpms. I think the idle air bleed is the issue.
But I'll take another look at it, as there's a stop on the carb as well as one way down over the transmission that links up to the carb.

FYI, we get a lot of complaints about Chinese carbs on this site.
IMHO you are better off rebuilding/repairing the OEM carb.

Yeah, I feel the same way.
The Keihin carb on my lawn tractor was flooding this past fall so I used a rebuild kit straight from Kohler,$100, new needle valve and all, tested it for leaks on the bench, installed it and all was good for a month then the flooding started again.
Polished the tube & valve seat the valve was in & it still flooded....grrrr.
Finally gave up & installed a $80 China carb, probably runs too lean but at least it doesn't flood.
Sometimes we never win for losing....
