I have found a crank on Ebay part no UA-22. And another crank UA-27A. will these cranks fit my AH crank adapter? Thanks, Jim.

UA-22 looks right. UA-27 is not.

Well I never heard back from the seller on the crank, so I built one.
Drained the oil and refilled. pulled the spark plug, cleaned and regapped. Weak to no spark on impulse. So I cleaned the points and now have a nice fat blue spark on impulse. Ran some fresh gas thru the tank and cleaned sediment bowl. Gas leaking out carb inlet so stuck needle valve. Carb will need a cleaning after sitting so long. Acetone removed the gum in the tank bottom and glass bowl.
I need a picture of the throttle control linkage as this engine just has the rod between the vane arm and the throttle shaft on the carb. I think it was some kind of adjustable spring, but would like to see some OEM setups to try to copy. Maybe it was like the lever and chain setup on the AEN engines.
Thanks for the help, Jim.

One AE I have came with a home made crank fashioned from a socket and a brace (as in, brace and bit). It actually works ok.

Here are some poor pictures showing the governor linkage. The air vane works against the spring, and the rod that goes through the shroud adjusts the tension on the spring to change the speed. Some of mine just have a nut on the end of the rod that you use to set a fixed speed. This one is set up for variable speed. The end of the rod where the spring attaches was rusted off, hence the odd-looking piece for the spring to hook to.

Zira, Thanks for the pictures of the throttle control. Does the knob and shaft turn and "lock" to keep the throttle tension in one position or just a clearance to hold the set position? Thanks again for the help. Jim.

Nope, just friction.

Thanks for all the help so far. Next on the list is to find a flatbelt pulley to fit the output shaft. I measured 1.431 inch. So , 1 7/16 should be close.
I have found some paper pulleys on ebay but none with the correct bore size. Is it possible to get an oversized bore and fit a sleeve in between to make up the difference? It won't have a heavy load, but I want the pulley to run true and not slip due to wobble. Any suggestions are appreciated. Jim.

You can certainly do that, any decent machinist can make it up for you. Unless you have a friend though, it may be a little pricey.

What size pulley are you looking for? I have a couple cast pulleys that came off Wisconsin AHH hay boiler engines that might fit that shaft.

Thanks for the offer. Looking for 4 to 6 inch diam and 4 inch width with a 3/8 inch keyway. I have some flexibility on the size. Let me know what you have and what its worth and we can work out a deal. Thanks again, Jim.
