Replacement Carb for Kohler K241

[KZK 7]

Can anyone advise where might be the best place to buy a replacement carb from.  I've looked on the net and there are a lot of Chinese ones.

Is your own carb missing or somehow not rebuildable?

Thank you for your reply, this stems from a problem I've had in getting the engine to run smoothly and across the rev range. I have replaced the coil, points, condenser and leads.  I can get it to run but only on a three quarters choke, adjusting the fast running and slow jets does have some affect but not sufficient  to make it smooth across the range. I am about to check the float chamber vent.  I am trying to run it without the air filter on.

If you have to run with the choke on Then you're headed the right direction With  the carb needing a clean out. 

 

 

Some folks have decent luck with replacement carburetors. 

 I'm not one of them. In particular on Big Block Kohler's from 10 HP up. 

 

Rebuilding one of these is luckily about as simple as you can get for a carb. 

Get a good quality rebuild kit and a replacement base gasket.

Following complete disassembly you can soak it in lacquer thinner for 24 hours. Use a couple cans of brake clean or carb clean and spray through every orifice from every direction several times.

 

Reassemble. Install. And let us know what the results are.

My go to for carb cleaning is an ultrasonic cleaner and some degreaser.  Pull it all apart, toss the parts in the basket, let it heat up, then run it through a few cleaning cycles.  The parts come out looking brand new.  I usually follow up going through the carb with my cleaning brushes and orifice pins, then spray down with carb cleaner.  Then reassemble with a good rebuild kit.  It hasn't failed me yet.  HF or Amazon has many size options.  I think mine is maybe 2.5 Liter.  Its pretty small, but is perfect sized for carbs.  I do wish I had bought a bigger one though, because I have found it so useful for cleaning other stuff as well.

 

Here is a little before and after from a pretty rare carb I have on one of my motorcycles.  It was only put on 1 model for 1 year in the US in the mid 80's, so getting a replacement wasn't really an option. I had to order the rebuild kit from some sketchy place in Indonesia, and it took almost 2 months to show up.  BUT, once rebuilt, I set everything on the carb per the factory manual, and it kicked over on the first try and idled beautifully.  Point is.....if you can rebuild the factory carb, do it

 

After seeing this, I thought for sure it was done for

 

All pulled apart

 

And back into service clean as a whistle

K & B Horse Parts had some fine looking carbs at the show. Check with them in the vendor section.

I have used carbs from Isavetractors( or something like that) and never had a problem.

kustomlawnandgarden There's plenty out there cheaper but I think these are top of the line.

I have gone both routes for any Wheel Horse I've owned or while I serviced them and rehomed them.  If you do go the replacement route, remove the bowl and spray the insides out really well.  Many of the replacement carbs had some gritty cosmoline-like substance in them.  Also, it is a 50/50 if your choke lever is completely opposite.  If so, I've reused original choke-plate shaft and never looked back, but this seemed to be more common on Magnum models.  It has been almost ten years on the imported one on my C165 and it hasn't given me any issue.  My original carb had such worn throttle shafts, and I had no reamers or other tools to complete the job properly, so I went that route.  Good luck!
