Carb Needle Stuck!

[Peteroo]

Hi All,

I am cleaning my carbs, and found one with the slide super stuck. Had to pry it out with something non marring(I removed the C clip on the needle). then noticed that the needle is stuck/corroded into the carb! This seems like a high potential for breakage and ruining half a bank of carbs. This would likely turn this project into a partout. Is there any way to tap the needle from the float side of the carb? Looks like the access is blocked off with a BB press fit into the tube. It is currently bathing in some PB blaster ( after an hour run in the ultrasonic w/heat). Next step i may crank heat up on US with some vinegar, after that possibly boil the carb, maybe try Kroil if PB doesnt work...PITA... Secondly, where can i just get adjustible needles instead of the whole kit?

I don't think you can get the needles outside of the kit.

Carburetor jets, parts and tuning items - Jets R Us

A co. that can possibly help you. Peteroo

for a simple carb cleaning it isn't necessary to remove the needle from the slide unless the needle shows signs of wear and needs replacement. you mean the slide needle not the float needle, right ?

[Peteroo]

Yea it's the slide needle that's stuck

[squirrelman]

leave it alone and move on being careful not to damage the diaphragm

Its stuck in the carb itself.

the needle will not stick but the slide may

i saw that only once before

judging by the corrosion on the throttle plate and needle it was exposed to an acid, probably mouse piss from a nest in the airbox.

sorry, but that carb may be beyond repair

how long was the bike sitting ?

Never seen that before in my life.. . .

Gdam.

Getting the needles outside of the kit is unfortunately hard. But that's why they can get $100 for ajwt not that only has $4 worth of jets and two needles.

I had a zx6 that had the mouse piss treatment. Was absolutely deviating to the bike. It mad it onto and passed the valves into the cylinders, it was brutal.

Shed storage is bad....

im a little worried that whatever it was made it onto the valves/cylinder. intake valves looks shitty on that carb side and it hangs up on something, possibly shitty spot on cylinder. spins to a tight spot, spin slow then the valve springs eventually rotate the crank. il do a compression test, if it holds il just run it and see if running it will burn it out.

That's brutal. Damn. Never seen that before.

Be careful with vinegar and aluminum. Getting it hot really accelerates the "cleaning" action. I ruined a set of tough to get clean carbs once. CX500. Not that the CX/GL were hard to clean. Just this particular set. No matter what I did, bike wouldn't run perfectly. So I tried the nuclear option. Crock pot of vinegar. It killed the carb bodies. Had to buy another set.
