Stuck Carb Jet

[digitalsam]

Ok, heat and cold didn't seem to work. In the end, I took the carb down to the local machine shop, where they thought it was a lost cause.

Looks like I need a new carb or set of carbs. unless someone is willing to take a stab at removing this one, I'll ship it to you.

Does anyone know if carbs from a 1979 or 78 will work on a 1980? There is a set on ebay right now.

Is anyone selling a set that will fit on an 1980?

Grumble grumble

The early type 78-79 carbs will work on the 80 and up motors, 99% plug and play.

Edm!

Hi Sam,
an EDM is an Electrical Discharge Machine.
AKA spark erosion machine, Sparkatron etc.
It won't be cheap and you need to find a company that has one.
Those gadgets will destroy anything that conducts electricity no matter how hard it is.
We used to mostly use them for removing broken taps at the bottom of blind holes and for making odd-shaped holes in one-off parts.
Fukkit, I know a guy who has one in his workshop. As a last resort and if you can wait a while, mail the carb to me and I'll see what he can do and what he'd charge to do it.

Do NOT send UPS or other private carrier, they will charge me a $30 "brokerage fee" which I ain't gonna pay.
Send via USPS parcel and mark the customs slip "no commercial resale value"

Sam,

As to the stuck jet, try a couple more machine shops. I had the same issue with a mixture screw in mine, snapped off the extractor. Took it to a machine shop and for $40 he got it drilled out down to the thread minor diameter. I then used picks and such to pull the rest out piece by piece.

Which carb body is it that has the jet stuck in it? Some members have partial sets, if they have the one you need, they might sell it to you.

As stated, any year carbs will work on any year bike almost plug and play. The XJ carbs can work, but the choke mechanism is different.

Thanks, I will check with another machine shop. I am also bidding on a set on ebay for $120, but that is another week out.

In the mean time, does anyone have a spare #2 carb body that they are willing to part with?

Don't know if you can get it in the USA, but NutCracker is like putting astroglide between your skates and the ice. Amazing product to keep in mind next time

Try a reverse drill bit

A reverse drill bit may remove the jet if done correctly.

Just make sure to go slow with GOOD hand cordination & select the smallest size bit that will still have sufficent BITE to grab the jet ... that way if it doesn't remove it you still have the option to go to the next bigger size.

It's out! Now for the cleaning

I got the jet out. Thanks for the offers of help. One of the maintenance guys at work was able to get it out.

Now, before I soak these guys in Chem-Dip I need to know about the brass parts, like the tube on the bottom of this photo and the tiny post in the tube where the needle goes. I guess Chem-Dip is hard on brass, not recommended to use it on brass or plastic/rubber.

Any thoughts? Is Chem-dip a bad idea? What about soaking the brass and aluminum in Acetone overnight?

[natemoen]

Do not soak them in anything like that unless you want to take all the butterflys off and pull the seals out. It WILL eat the seal on the butterfly shaft. Dont know about the brass parts though. If the stuff says not to use it on brass then I would not use it on the brass.

I have soaked them in a pinesol/water mix. It get the crap out and cleans them up. If you leave it in the pinesol to long they will start to corrode so I only soaked them for about 5 hours and then washed them off with some water and then I soaked them down with wd40 to get all the water off and out of the holes.

Hi Sam,
referring to your photo, remove the float needle seat to clean behind it. There's an O-ring there too, that soaking would not be good for.
The main thing not to soak is the carb body unless you want to go through all the hassle involved in removing and replacing the butterfly shaft to install new butterfly shaft seals because the carb cleaner will attack the old ones.

Like Fred stated, remove that phillips screw you see in that picture and the plate it holds down, then you can remove the float valve seat. It has a screen on the bottom for catching crud you will want to make sure is clean as well as the inlet fuel passages to the T's.

Teh butterfly shaft seals have been covered pretty well already by Fred and Nate.

If you really want to dip the carbs, use the Yamaha carb dip, which is safe for rubber seals.

How Do That Voodoo Do What Couldn't Be Done???

And just what tools/techniques worked to remove the "unremovable" jet?



I'm all prepared to hear that your maintenance guy is an apprentice of Uri Geller and can bend spoons/remove stuck jets with the power of his mind alone...

Yeah, he and Uri go way back. My guy can actually bend over and touch his toes... Not sure about spoon though.
