Carb shaft bushing install instructions?

[Mudrig150 298]

If you still need to know... The butterfly screws are 3-48. If they're broken off, you can easily drill them out to 4-40. I used self tapping, Philips head 4-40 screws in my choke shaft that had 2 broken screws, and bumped both screw sizes up to 1/4" long. The throttle shaft threads got cleaned up and I put new flathead brass screws in. A little bit of threadlocker blue on them, and they are never coming out.

I believe I used McMaster Carr 92453A092 for the 3-48 and 93878A106 for the 4-40 screws.

Blue threadlocker will only provide a bit of resistance, I would peen the ends of the screws a bit to be sure that they stay put.  If removal is required in the future, grind off the distorted portion.

Really... almost thought for a minute you sent it out for polishing!

I'm up for a new can of carb cleaner … will try Gunk in stead of Berrieman's next time.

Polished. Yes. But not sent out....

Just takes time and care.

 

Putting Berryman's up against Gunk is probably a tomato/ tomahhto.

I think you'll find that they are very comparable to one another. Some people swear by 1.... Or the other.

 

Biggest thing is to just try to be patient.

Soak... Scrub... Repeat as necessary.

 

The wire wheel I use is on a 6-inch bench grinder. It's made of soft thin steel wires and is fairly narrow.

I do believe the Berrymans has a bit more solvents to tackle the "varnish" in those most tiny passages again JMO, ... Have you ever tried a tumbler (like for gun ammo brass "reloading") to polish small parts like those carb pieces ground corn cob would be the media of choice and can be remove with a blast or 2 of compressed air... And no metal needles to bite finger tips or assault your face/eyes .

[WHX?? 48,833]

Interesting idea Billy, ain't worried about the media getting in small passages? My wife has got one of those rock polishers I bet a carb body would fit into. Be alot less labor intensive I would think? 

[JCM 9,180]

When I laid my eyes on that carb yesterday that @ebinmaine  had cleaned up I couldn't believe my eyes and asked if that was a new one and can honestly say I have never seen a carb that old look that good. When that boy takes on a project he is super meticulous with his prep work. He definitely has a not so serious side to him and can be very comical for sure, but when he puts his mind to a project boy is he FOCUSED.    He is a great guy !     Also would be a good person to buy a WH from.

I've heard the same thing multiple times.

Online and in person.

 

To be honest the reason I bought Gunk was it was available locally for about 12 or 15 bucks less.

Thanks for reminding me about that....

I've been mulling over getting one.

 

Originally for all the hardware we reuse but it certainly would have great value on carbs as well.

 

 

 

@JCM I appreciate the vote of confidence.

Thanks man.

You're "alright"  too.

The ground corn cob doesn't get too small... https://www.harborfreight.com/520-lb-Rust-Cutting-Resin-Abrasive-Tumbler-Media-63672.html ... https://www.midwayusa.com/case-tumbler-media-and-polish/br?cid=19907 ... But as you can see there's many more ask Josh @PeacemakerJack when he does his cowboy action shoots what he uses during his reloading sessions...

Well folks @JCM Jim stopped by the house today and graciously put up with me for a bit.

@Stepney here's the carb info...

 

We removed the throttle shafts from my old C160 carb and his C165 carb as well.

Both were some floppy & both were broken at the top linkage.

Here's a video I made awhile back that shows the carb I have.

 

 

Jim's was not quite as bad but broken in the same place.

 

We soldered the top joints back together.

Cleaned his up some and pressed the 2 bushings in place on each carb.

On his carb I used a dead blow hammer with a 1/4" pin through the carb body to hold the 1st bushing straight. Then press-fit the 2nd one on in with the vise.

 

On my carb I just used the hammer for both.

Each method worked out fine.

We put the throttle shafts and plates back in with new 3-48 x 3/16" button head Allen screws. Added loctite for good measure.

 

 

See the above video or the pic a few posts back for a "before"...

 

Here is my C160 carb after cleaning.

 

 

 

If you look carefully under the linkage you can see the spacers we installed.

 

 

@WHX24

This method turned out to be FAR easier to do than we thought. 

 

I have 2 other carbs that I'll be repairing the same way.

 

I now have another reason NOT to buy a Chinese clone cheap carb.

 

Thats top sheilf work Ebenmaine!

[WHX?? 48,833]

So what yer sayin Jim @JCM his work is a bit better than his smell?!?!?

 Heard tell his shower is in a privy!  

Seriously EB good thread as I admit I got more carbs that need this fix than I would care to admit, I just keep going Chinese cause I ain't got no time! Swear to God Jim this last infloor job I'm retiring!

What with the MN boys coming down on us to "stay orginal" I'll admit  seems easy to do.

[JCM 9,180]

After seeing that carb of his I was about to throw mine in his wood stove and say the heck with it and go chinese, and have a Mai  Tai  and celebrate.

[WHX?? 48,833]

My gut is hurting Jim!

[MikMacMike 479]

Hmmm Im working on my carb right now and have to identify it.....all i can see on it barely are the faint numbers on the flange that say I think 6636 with what it looks like a KO after......I need to get a rebuild kit for this, I dont even know if its the right carb for this engine....K301

Could it be 236636?

Found this

https://www.partstree.com/parts/kohler-a-236636

 

One of the replacements 4785331 is listed for a K321 and M14.

It is listed in this manual which has left and right pages in book form. Makes it hard to follow. The carb numbers could be on the left or right side of the page.

[MikMacMike 479]

Well guess what.....all this time I thought i had a k301....while looking for a kit for some reason thing wernt adding up or matching. Then I started to question what motor I had.....even after I had cleaned and retorked the head back on....well off it came. I would not have been able to sleep if I didnt measure the cylinder bore to identify the motor......DAG NABBER  I dont have a k301.....its a k321....what a bonus. Ive had this WH since 2003 /2004 not really sure, anyways all these years I beleived it was a 12 horse 301.....Yes I slept like a baby after that hahahaha

 Great pics and write upsThe throttle shaft on Big Oly is as loose as @WHX24's wallet at a tractor show. It's my plow tractor and with winter still here I didn't want to mess with it. but I have another carb I think was originally on Skonk that will be going on the 953 so whilst waiting for the Super Bowl  I decided to get it ready in case I needed to do a swap in the middle of a storm. (I did rebuild a Chevy Vega carb outside at night during a lake effect squall in my college days but that's another story)  After soaking in Gunk, a session in the ultrasonic was completed and it was time for repair

 

tool of choice the Dremel

 

 

 

The hole in this carb isn't bad but enough to fix

 

 

After dremeling ,another session in the ultra sonic

 

 

I drive the bushings in with a 1/4" socket

 

 

 

I use a dab of grease on the screwdriver and green sleeve and bearing retainer on the screws

 

 

Ready for work. When I yank the 953 carb off, I'm going to try the vibrating tumbler method on the carb body.

Nice work Mike.

Thanks for posting!

Mike did you ever do the tumblerizing on that carb?

Nope never did. The carb body is too far gone. I still have it. Maybe toss it in there for the EEck of it someday when I'm bored
