F932 Carburetor kit

[ahayden]

All,

My F932 isn't running as good as she used to. I think it needs a good carb cleaning. Looking in the JD online parts catalog I don't see a carburetor kit, just the individual parts. Anyone know if such a kit exists (gaskets, seats, mixture screws, etc)? I'd prefer to get it all in one kit rather than buying a la carte.

What are the actual symptoms ? I have a diesel version and it was running rough. It was the rubberized connection between the engine and the transmission. So, check if it's fuel or air as well as mechanical.

Rather than disassembling the carburetor for a "good cleaning" I'd try adding Sea Foam to the gasoline. The engine should still run at seventy percent Sea Foam but you don't really need that high a content to clean the passages. It does the job well. As a second choice try eBay or Amazon for a complete carburetor. You may find a complete new carburetor for about the price of a complete kit.

Hard starting, poor idle, surges at wide open throttle. Sometimes it doesn't throttle up and I have to manually move the governor to get it to. Plugs and air filters are good.
I've never used any of those Sea Foam like products. I've been leery not knowing what bad things they might do. Might have to give it a shot.

I'd never used Sea Foam either, until I did. I have a pressure washer that would only run at low throttle settings and with the choke set. I ran it for a bit on a 50/50 mix of gasoline and Sea Foam. I saw no improvement. I left it overnight. I guess Sea Foam did some magic overnight as the next day it started easily and ran normally. I have no connection with the company but I'm a believer. Check out You Tube for other good results. A local rental place uses Sea Foam in all their small engines and it has really cut down on their shop time. At worst you're out the price of a can of Sea Foam and back where you started. At best your problem is solved. I also run non alcohol gasoline in my small engines and add Marvel Mystery Oil to the gasoline at about an ounce per gallon. At the end of the season I drain the fuel then run the engine until the carburetor is dry, too. I REALLY don't like carburetor trouble!!

Doesn't it have a Yanmar engine? If it does you might see if kit is available as a Yanmar part.

I guess I wasn't entirely accurate. I did inadvertently use an "additive" once. My dad had a motor home with a carbureted 454. It had a random hiccup that would occur every now and then at highway speeds and acceleration. He had his own in ground tanks and fuel pump. Once when I was young he told me to fill up the tank as we were getting ready for a trip. I accidentally grabbed the diesel nozzle (it was one for gas, not the specific one for diesel). I had pumped quite a few gallons in before I realized what I had done. As soon as I figured it out I stopped and told him. At that point there wasn't much that could be done easily, so he finished filling it with gas and hoped for the best. We took it on a long trip and had zero issues. Even better the random hiccup was cured as well.

I'll have to pick up a can of Seafoam and see what happens. I've always been afraid that those additive things will attack something (gaskets, seals, hoses, etc). or do some other not-so-good things and then I'd end up with worse problems than I had.

Jaxs, I did think about seeing if something is available through Yanmar. Admittedly, I haven't looked. It's been my experience that JD likes to put special components on what would otherwise be a standard engine. The oil pan on the Kohler in the JD 400 lawn tractor is a good example. Don't ask how I know. The trick is figuring out which Yanmar variant is closest to the unit used in the F900 series mowers. I'm not certain how to sort that out.
