Many thanks to everyone who took the time to help think through this problem. Today I removed the carb with the fixed high speed jet from the JW 22 and after changing the tank to carb connections put on a leaky carb from a JW 16. Motor started on the second pull, ran great and after a bit of fiddling idled down to a quiet purr. Obviously, the original carb that I overhauled has a problem. The leaky carb from the JW 16 is in another post.

July 12, 2024 at 10:07 pm #289107Indeed. With the older carb the motor is “normal” even with sub average compression. I think there may have been a problem with the carb from the beginning. For a three, it’s not all beat up. Barely used. The Red book doesn’t have anything on the JW 22 and nobody seems to know much about how things changed with a carb with no high speed jet. The bowl is slightly different from the older model.
Anyway, again, many thanks for pointing me in…a direction. Now, onto the leaky JW 16 carb which the JW 22 seems to love.
July 13, 2024 at 8:33 am #289112that carb is 57 years old and previous owner surely ran that engine without headaches.
The structure of the carb did not change and remains a bunch of passages and ” holes” to let fuel sucked in
did you try to install it on the other JW you got the “working” carb from
Although I know you cleaned it did you run some small mono or “carb brushes” in all passages.
Some folks have been known to plug up the air intake to the carb …..thinking the lead pellet had dropped out !
compare your good ” needle” carb with the jw22 … & check parts diagram ..
aside from the hs jet and cover bolt look for any missing or ” extra parts” ! did you open up the air silencer and clean out any bugs
p.s. … could not remove left jpg. 🙁

July 14, 2024 at 11:10 pm #289161Yes, yes, and yes. That leaky JW 16 carb? I took it apart and replaced everything with a new carb kit. Much better jet packing washers and new float needle and carrier. No more leaking. Put said carb onto the JW 22. Started first pull. Warmed up and dialed down to a fast idle. “Slow” is at the “S” of START and is barely ticking over. Below that it quits.
I tried the fixed high speed carb from this JW 22 on another JW that was good. Still didn’t work. Pics of the JW 22 attached. I hope.
