mkirsch 09-04-2012 05:37:57 64.80.110.74 Report to Moderator	I can't get the needle to stop leaking on my Super A. It's a new needle and seat, along with a new float (old one was smashed and leaking). Take the carb apart, clean it out, reset the float, check the float/needle action, put it back together, and the next morning: drip-drip-drip. Take the carb apart, clean it out, reset the float (it hasn't changed, still correct 1-5/32"), check the float/needle action (still pushes the needle all the way up), put it back together, and the next morning: drip-drip-drip. Take the carb apart (again), clean it out (clean as a whistle from before), reset the float (STILL hasn't changed), check the needle action (no difference from before), put it back together, and the next morning: drip-drip-drip... What is the secret to making these %$#@ things work? It's all I can get. The kit was an A&I off Ebay. CaseIH dealer gave me the EXACT SAME KIT, only twice the price. [Reply]   [No Email]

I use a little permetex on the carb body( let it dry good).Seems to work for me.   [Reply]  [No Email]

I have a professionally built, restored , show condition carb, 90 day warantee, carb in a box looking for a home. And you can sell Old that core for 150 dollars. Or I will give you $40 dollars for it on this one. Email is open.   [Reply]  [No Email]

Then with a good non sparking light I would turn on the fuel and watch for leaks to start. Knowledge is priceless, supposition is baseless. Jim   [Reply]  [No Email]

Not much room in there, and a slight touch along the side means a high fuel level, possible flooding. Ihave to be careful setting my floats, in the exact center of the chamber.   [Reply]  [No Email]

If it is coming out of the nozzle it is indeed caused from fuel level too high and most likely cause is the needle and seat. But, they can leak around the gasket on the seat and cause this also. I have got to the point that I use loctite teflon sealer on all those to overcome that leak from rough castings. I find most needles that leak are due to the hole in seat not being true. Some you can see with the naked eye that they are oblong or have a poor seat. I use a suitable tool to stake that seat. Nozzle pintle from like a 414 works great. I never tap on the viton tipped needle because they just turn in there anyway in use.   [Reply]  [No Email]

Also did you put a gasket on between the carb body and the needle seat? Did that once and it leaked around the threads of the seat.   [Reply]  [No Email]

Gasket, or no gasket? There was a gasket on the old seat, and I used the new gasket that came with the kit. I have no idea how to tell if the float is dragging.   [Reply]  [No Email]

As for the float moving the way I do it is this. Take the turn the carb right side up and then upside down a few times. Listen for the float to move and if it moves freely you can in fact hear it move   [Reply]  [No Email]

When you had carb off, did you pressure test needle? You can do that by blowing in fuel inlet and see if thatis the actual culprit. Sounds like u have, as stated, a cracked body or plugged vent. I use A&I carb parts and have no trouble.   [Reply]  [No Email]

Open it up. Drop the needle in the seat then tap on it a few times with a small punch etc. Do not whale the crap out of it just a few light taps. Pull it back out and you should be able to see a ring on the tip, that is a set. Learned that from and old carb guy years ago but has is long since 6 foot under   [Reply]  [No Email]

Cannot speak from experience. HTH, Hendrik   [Reply]  [No Email]

Is the float rubbing the side of the float bowl?   [Reply]  [No Email]
