81' Ironhead carb issues
#31
The plugs that were in it were Autolite Platinum AP64. The plugs that I bought were the Autolite 4123. There was a jet under a little plastic cover that had a lever on it. It is located on top of the carb right behind the flange that the manifold mounts to. Over close to the choke linkage there is a hole, looks like there should be a jet there but it is just a hole. I will try to post pics this evening.

The hole is supposed to be there. I do not know its function. It is usually [mostly] covered up by the choke cable bracket.
Under the white cap is the pilot screw. It should have the screw, spring, washer, and o-ring, removeable with a pipe cleaner - screw it in sort of. Often they come out on the first try. Other times you need to fiddle, be creative, etc.
The two jets, slow and main, are inside the carb, beside each other. The slow jet is under the rubber plug.

im not being a jerk here just putting out an f.y.i ----you should have checked the ignition first.its the easiest cheapest thing to do and it eliminates so many problems if its good.------just check for a spark.a good spark.then go from there.
did you check and see if you had points or not?

The right side engine cover is the gearcase cover, commonly referred to as the cam cover as the cam gears are behind it. The small round cover on the "nosecone" is the timing cover. Remove the cover and let us know what is in there. Best is to post a pic.

O.K. lots of things poped up today and could not find the time to get in the garage But tomorrow I will get out there and tear into the ignition. Still not sure if it has points or not. I will post some pictures of it as soon as I gt it opened up. Thank you guys for all of the advice, I would honestly be lost without you all.

That is the sensor plate for an electronic ignition. I have never seen the original EI for the 80 to 82 Sportsters but i would guess that is what it is. The only place to get info is in the factory service manual 99484-85. The related computer module should be mounted on the bottom of the battery carrier/oil tank.
Look and see if there is something there. It may be roughly rectangular with sort of pointed ends, attached with two bolts near the pointy ends. It would have a ground wire, a cable with two wires [white and black] going to the coil, and another cable going to the sensor plate.
