Just had a thought though, can you post a close up picture of the distributor?
I can hear a cylinder fire but nothing else. I'm going to give my local NAPA a call to see if they do. I'll try to get a picture.

I ran into a issue on mine that sounds exactly like the problem you are having with yours, but I dont want to confuse the thread if your engine has a different distributor.

If you cant post a picture I can post one of mine for you to compare yours to, if they are the same there is a set of gears that are supposed to be greased One shot of grease every so many hundred hours. There is only a plug there no grease fitting and most people are unaware of this and they never get greased and wear out! IH didnt put fittings there for a reason too, you can over grease it and cause problems thats why they opted for plugs insted of fittings. these gears are available and i got mine either from steiner or All States AG I cant recall that was over two years ago.

seperate it at the timing cover and inspect your gears best i recall the worst that can happen is you can get it out 180 degrees so pay attetion to where the rotor is pointing before you take it apart. can you see the slotted plug in the picture? thats where I installed a grease fitting. there is a thread i started here on the stak I dont recall which subfourm either aircompressors or farm tractors about the issue i ran into. gears were cheap.

I was wondering what the plug was for. I hate taking off the distributor but I guess it has to be done.

while you have the dist out you can set the points or double check your work on the work bench. mine ran like crap and finally quit, all new parts same as you before i found the actual problem. was a real hair puller until i found the cause.

I don't know how far you are from NY, but, if you can get it to a Cubfest we're having, Columbus day weekend, there will be a bunch of cub owners there, that can help you. Check farmallcub.com forum, for Northeast cubfest, or PM me if you need info.

So I sent the carb in for a rebuild. Steiner carb parts were wrong. I now have ignition and it really wants to start. Strange popping noise coming from the oil cap.

Have you run a compression test? If your description of popping at the oil filler cap is accurate, you may have issues with rings or a burned thru piston. I also have had a issue with after market points, The points for a newer distributor are different from the old tractors. Trouble is the application listing on some listings on the package are wrong, they wont work as the rub block on the set is in a different position. therefore the points don't open at the same place it needs to and the internal timing in the dist. don't match the rotor cap.

UPDATE: Had my local mechanic take a look. It was a blown head gasket! Here I was doubting my competence when in reality everything I did was fine.
