Johnson A21092

[froggy]

I am looking for information on a Johnson A21092 that I am beginning to clean up and for a Johnson Carb to fit. Carb bowl says, Johnson Motor Co. South Bend Ind. Model O. I posted in the Ads to try to find one. Trying to stay original, but may be hard. Have an AB that I plan to work on next and that carb looks the same. If any of you know of an alternate or different year that would work, please let me know. The A21092 has got to be pretty early, but I haven been able to find the model number except the prefix A. If you can give me more information I would appreciate it.

Your serial number, is listed as a 1925 which should be a 1925 A-25 2 hp

To my knowledge there is no rebuild kit for those…

I have somewhere in my stash of paperwork a Johnson interchange for parts on the early motors…
My guess is that unless your carb is broken in pieces or missing some major component it is probably ok.

Re-reading your post kinda leads me to believe you do not have a carb.

Is that correct?

A carb from any 2cylinder Johnson serial #506 thru#44977,will fit your motor.

Richard and Stanley , thanks for the replies. I realize now that I messed up on the post. I have recently gotten two engines. I was looking at one engine and thinking the other. One is the AB-25 with the brass lower unit. That is the one which has a bad carburetor. It has a carb, but I don’t know enough about how they are supposed to look to know if it is complete. I also have an engine A21092. No dashes in the model number. I am attaching pictures of the carbs on both engines. The second picture is off the A21092. That carb looks complete. It has a what looks to be a wood kill switch. The other picture is the AB-25. Note that it looks like the top of the carb is gone, but unlike the A21092 it has no screw holes to attach a top, but the plate inside seems to slide on the rod and there is what looks to be a retaining spring that touches the rod. Note the A-25 has a bakelite or fiber kill switch instead of wood. The carburetors on the two engines are completely different.

I appreciate your help. I would like to bring these things back to life.

Here’s a picture of carb top and kill button on A25.Your#21092 should have same carb and button if it’s a Johnson.From what I can see it’s carb looks like from a different make of motor.Do you have a picture of the whole engine?

Stanley I think it is the same carb on the AB-25. Apparently there is a cap on the bowl held down by the spring wire shown on yours. The bowl Cap on mine is gone. Other than that it looks like your picture. The A21092 side view picture attached is good, but the other two aren’t as good. One is a front view and the other shows the kill button. It is definitely a Johnson according to the flywheel. I read somewhere that the later A s did not have the raise lip on the top of the flywheel? Is that correct?

Your new pictures show a Johnson light twin that has had some foreign parts grafted on.The carb looks likes it’s from an Evinrude of some type,and stop button is home made replacement.The early “A” model fly wheel has a concentric raised portion in the middle that extends beyond the rope plate.
