Carb cleaning help?

[Guest]

I'm trying to save the carbs I got on this gs450. They have been sitting for 6 years and are stuck. This is what I got so far. I heard about having to drill parts out? Not sure if genuine or bull ****.

I'm trying to figure out if this carb is ready for a bath yet. I don't know if I am missing something with an oring somewhere or not. Any advice, or you guys think I'm good to dunk this bad boy?

I couldn't post more than one pic, so here is a Imgur link. https://imgur.com/gallery/sLtj7

Thanks for reading!

Drilling really only necessary if something snaps off. (maybe the pilot jet?)

Soaking is always good and my release any stuck parts. Blow through with an air line. Look for poor mating surfaces with signs of corrosion.

Find a list of parts here

I have restored 3 wrecks that were sat outside for
up to 20 years .....
On all of them I have done the following.

Carbs off , strip internals and simmered carb bodies for 30 mins
in a lemon juice and water solution.
(1-2 bottles lemon juice in a big fish steamer I use)
Can take banks of 4 carbs without splitting)

Carb cleaner and blow out all bits , jets.
I use thin welding bits cleaner wire for the jets.

This has worked for me on carbs that looked in a
terrible state. All the bikes are still in use and fine.

(Use fuel filters if they can fit on , it
would have saved my sanity when starting
up the bikes for the first time )

Looks like your ready to dip them. The `drilling' is normally to remove a plug that the factory uses to cover up the air/fuel mixture screw. It looks like it has already been removed on yours. If your using carb dip, as long as all the rubber is out then you're good to go. Don't put the slides/diaphragms in.

Thanks for letting the input everyone! I'll try finishing up the cleaning this weekend. Just didn't want to toss it in the Chem dip with rubber somehow getting missed. I'll let you know how it goes.

Guess no one likes lemon juice !

I for one like using lemons .

Did you remove the pilot screws and pilot jets? From the looks of your photo the jet needle was not removed?

Which one is that? You mean the copper pipe sticking out with the holes? That appears to be part of the main jet fuel tunnel thing I think. It lines up with it perfectly.

No I love using lemon juice to clean stuff.

Remove all bits from carb bodies , set aside and clean.
Simmer carb bodies with nothing in for 30 mins.
