Thanks jb, yes it was a nice restoration with quality parts and paint. I know what you mean about those little clutch dogs. The pin is not easy to deal with. Did you use the spacing washer to make them line up with the inside slots on the plate?

I should have said a piece of the dog broke off.

I took the crank and rod to my Whizzer parts supplier to get them welded up and machined. While I'm waiting I decided to check out his automatic clutch. Overall it's in good shape. Needs cleaning, new bearings and an engaging dog with pin.






The arm has a chunk out of it. Maybe it was ground out for clearance. I'll find out after cleaning it up a bit.







The magneto coil will be getting a new spark plug wire. Get rid of the condenser in favor of a point eliminator. Then replace the plug cap with one that's more Whizzer.





The carb is pretty nasty inside. It should clean up nicely. The spring and ball that holds tension on the choke shaft is missing. I think I have those.





The belt guard had a couple of cracks and bends, but is still presentable.

I was able to purchase a correct dipstick. And the chunk out of the clutch arm was ground out. Ray says he sees that a lot on clamp in motors to clear the top mount. So I'll smooth it out and make it looks like it belongs.




I got all the clutch pieces cleaned up and ready to reassemble with new bearings and replacement engaging dogs. May need a new felt washer. Still need to rivet the linings back on. They are good and thick.





John Koehnke brought my rebuilt crank and rod to Donut Derelicts, and I didn't need to drive to Orange and pick them up. Came out real nice at .030. The original crank wouldn't clean up even at .050 so I used one of my other used ones. Have to figure out what to charge for an outright crank (no core trade in). The rod got it's dipper repaired and Fred Koehnke said it was bent also, so he straightened it and made sure the small end bushing was the right size.

I got to hang out with Ray (mason man) most of Saturday and talk Whizzers. Had a great time. He's a wealth of info and just a fun guy.

Today I finished cleaning all the carb pieces. I will assemble after I get a new cover gasket.





I also repaired the plug wire and soldered a silicone cover wire that goes to the points/eliminator. The owner is a hot rodder from way back and I know he'll appreciate the Rajah plug clip.

Couldn't find a gasket soon enough, so I made one.








The carb went together smoothly. The only issue is the fuel mixture valve has an o ring, but my buddy Dan made a punch for his Tillotson to make a leather packing. That should finish it.

I cleaned up a bunch more parts. Next I'll paint the cylinder, lap and install the valves and chase all the threads to make sure it goes together with the correct torque specs. Maybe file all the extra flashing off between the fins to give it a nicer look. The head has a few broken fins, so I'll Dremel the rough edges and shine it up just a bit while trying to keep the original look.
