Got a "new" CA.  Cleaned carb, installed new points and condenser.  Gas is new and clean.  Got her started and it ran fine for about 3 minutes, then it started to rev briefly, then slow and pop pop, rev, then pop pop.  After fighting with a bit, it wouldn't even pop anymore.  Some additional data: points were firing, plugs are little oily and maybe fouled, wires do not appear to be copper core, different carb from my working B didn't change anything, I adjusted the governor cross shaft to specs.  Any ideas?  I'll start with new plugs and wires next weekend.  Thanks.

Put your old condenser back in. Had a D17 doing exact same thing after a fresh tune up. New condenser was junk, nothing is made like it use to be.

Dang.  I used Agco parts made in usa, but I'll try anything once.  Thanks for the suggestion.

When you changed carbs to try the one from your B did you check to see if you had a good flow of fuel getting to the carb? Take gas line off carb and flow check it into a container for about 30 seconds or so.

I didn't do it for 30 seconds, but about 5 seconds (both carbs).  Flow seemed to be good. However, I will try it longer.

If you have good fuel flow then see if it starts again when cold. Could be a cracked or warped manifold that opens up when it gets hot and pulls too much air in. If it's pulling outside air it may not be pulling enough vacuum on the carb to pull the fuel mix into the cylinders.

Do you have a old Chebby setting around with points in it? Use that condenser, same thing. Leon R Cmo   By the way did it run all right before you started working on it? If so use that condenser.

Steve,
Didn't take you long to get on the tractors!  Is this Barbie we are talking about? If so that might explain it. Did you pat her on the hood and tell her she is the best one of the bunch???:)
I am the same way, new toys are meant to be played with! I chased some things like this on the WD this winter. I believe I did have a intermittent fuel flow and maybe bad fuel also problem. from the way you described it I might check the fuel system out first. These guys had me squirting some gas in the carb and that pointed me towards fuel issues.
BTW Sandy Lake is about 40 minute drive south from me. Looks like you may be ordering more stuff. Tell Brenda I said Hi! She is pretty darn good at getting you the correct parts for your old AC's.
Regards,
 Chris

A new set of plugs n' wires is a very good start. (No pun intended) You'd be a bit surprised how a old set of plugs will make an engine run real lousy. On the fuel flow test, ya havta' go a lot longer than 5 seconds. Let it roll for a minute or so and watch it close. If you have a glass jar you can drain the fuel in, this will let you see of there's any debris in the fuel by looking through the side and the bottom of the jar. I have an old pickle jar I use for that test. Works great! Sorta sounds like Ignition though since you tried a proven Carburetor and it still acts the same. Get them new plugs screwed in that thing. And don't use Chimpanzes either! Put a real spark plug in it.. LOL!

Chris,
I talked nice to Barbie the whole time.  The other CA is Ginger.  Sandman let me change me mind on the loader wide front, so I now have two narrow front--one is a single wheel front!  I'm stoked!  I like the old Texas patina on the hood and tractor and plan to clean her real good and clear coat the original "paint."  There is a lot of the other orange too.  I like the original look.  I will get her torn down and rebuild everything and get her running good.  She will be a sleeper. 
Steve, Thanks for the input.  I changed the wires tonight and will get new plugs Friday and give her another go.

Grinder.  That's what it was.  I put a different condenser in and it worked fine.  Dang.  Thanks for the help.

Glad to hear it was something simple. I was fighting with my CA just a couple weeks ago. It was a fuel problem and I for the life of me couldn't figure it out. Had carb rebuilt and still wouldn't work. Took carburetor back off and ran up to AC tractor salvage and had Chester look at it, he didn't see any reason it shouldn't work then said something about the gas I was using. Well I never even gave it a thought as I just bought the gas last fall for my gleaner F combine, drained it out put new gas in and boom, fired right off. Again something so simple it will drive you nuts, and like I said before NOTHING IS MADE LIKE IT USE TO BE. All you get now is junk that won't last.
