The double nut method is very effective, but this is the gold plated solution: http://buy1.snapon.com/catalog/item.asp?P65=&tool=all&item_ID=10336&group_ID =1247&store=snapon-store&dir=catalog You have to have the size for your stud. Try e-Bay. Here is another helper: http://lpslabs.com/product_pg/lubricants_pg/LST.html Re-install the studs with the same tool or the double nut method but use anti-seize compound. http://lpslabs.com/product_pg/lubricants_pg/AllPurposeAntiSeize.html Doug Dodson Glasair II-S FT Flight Test Engineer, CFI-A/S&MEL/I/G -----Original Message----- From: owner-engines-list-server@matronics.com [mailto:owner-engines-list-server@matronics.com] On Behalf Of Michel Therrien Sent: Thursday, February 10, 2011 6:46 PM Subject: Engines-List: Carburetor stud removal Hi!

What do you mean by a "split nut"? Then use THREE nuts OR get a stud removing tool. Make sure the nuts you use are HARDENED NUTS. NO cheap Chinese or Home Depot CRAP! Line up the flats of the nuts so you can put a 6 Point Deep socket over ALL the nuts. NO cheap 12 or 16 Point sockets. Use LOW impact vibration either with a impact wrench or a Tap Hammer. Heating the stud is WRONG. When you heat - You heat the expandable part so it moves AWAY from the part you want to remove. Of course this is an aluminum casting so you DO NOT want to heat it. Get some PB Blast or Mouse Milk and let it soak it a shallow pan with it over night. If things get stripped you will have to install Heli-Coils. How are you holding the carb while you try to remove the studs? Barry On Thu, Feb 10, 2011 at 9:45 PM, Michel Therrien wrote: > > Hi! I bought a carburetor and had it rebuilt.

Structurally it looks like they are in far enough to properly secure the carb. Is there an interference problem with them not being threaded in all the way? Or are they the wrong length for your application? If not I would leave them and run it. If so the methods described by evryone should work. Double nut and heating the case around the stud. Most stud extractors I have seen/used can damage the stud, especially the threads where they grab it. If you use one you may need to replace the studs. Of course if they are the wrong size it may be your intent. my $.02 Mike On Thu, Feb 10, 2011 at 6:45 PM, Michel Therrien wrote: > > Hi! I bought a carburetor and had it rebuilt.
