I'm rebuilding the carburetor on my 1949 JD A. I cannot figure out how to remove the "nozzle" that is in the carburetor stem and runs up inside the carburetor. I want to remove it because my craburetor needs a real good cleaning. Is there some tool or how should I remove the nozzle? Thanks.

I hear of all kinds of gadgets and taps etc. I have had good luck with most of them ideas, however if you want a easy no brainer / --nozzel removal for idiots-- type of game plan try this. Go get a assortment of self drilling hex headed screws if you do lots of different carbs. Do NOT confuse with self tapping. If you are doing just one carb you will need only one screw for your particular carb, that and a fender washer or two, is all you need. And if you happen to have a cordless drill it is as simple as running in a screw. Always make sure you sand blast or bead blast the bottom of the stem so the rust does not fight nozzle removal.

The reason I suggest this method is I have got quite a few carbs to fix with a broken off tap inside the nozzle, probably due to the incorrect drill size or a unsteady hand while tapping then out. I can honestly say that is a major pain in the rear end to try to dig out a broken off tap up inside the stem.

Just in case no one else mentions this, you have alot of forgivness (or space) from the bottom of the nozzle to the top, common sence is a must however. Good luck NE IA Dave

Andy, Use a tap to cut some threads in lower end of nozzle for a bolt to grab it. The threads won't hurt anything and sometimes the tap will pull it out by hand too. OTC tools made a little slider hammer for JD to pull those nozzles out with. If you don't have a slide hammer or dent puller to grab the bolt you can just use a longer bolt or piece of all thread rod with a piece of tubing extra large washers and nuts and pull it out by turning down the nut on bolt. Sometimes it takes a little heat on the carb casting too. You don't want lots of heat on the nozzle or ruin or distort it. Don't want to try pushing nozzle out from top either or can ruin it. If nozzle does get ruined they are available new again also from JD, Roberts Carb, or myself. Good luck.

I got a small slide hammer set from Harbor Freight that has worked well. I had to make another tapered end for it as my original tip broke off from soo much use.
