A couple of engines I picked up today

[tomc]

I picked up a Briggs and a Clinton today. I needed the Clinton for my Cheeftah project.
The little Briggs had an interesting decal that seems like a good name for a mini bike but it was an edger.
Look how the decal was applied, across the flywheel cover and the other piece of sheetmetal.

The Clinton has a strange clutch/brake set-up that I have not seen before. Anyone recognize it?

I have an old Clinton parts book and will look up the numbers on the Clinton to see if I can figure out the model year.

I'd say it's a great name for your bike with the tiger on it. Looks awful close to an original Cheeftah decal.

I may be wrong, but that thing on the Clinton looks like n old Comet torque converter. Is that what you were asking about?

 

[tomc]

Yes. The pulley on the crank I have seen before but the extra disc has me puzzled. It looks like it could be a brake disc but???

The back piece is from a older Comet 30 and what left of the driven. Nice scores.

 

[tomc]

Researching Comet clutches, I have not found a match to figure out what all might be missing.

 

[sparkwizard]

That is a torque converter. It's like a jackshaft. Look behind that plate. There should be a sprocket for the chain driving the wheel.

 

[chrisr]

Here you go, you have the Comet 30 TAV1. There is not much left of your driven, bascially the backing plate is all...

Thanks all. I will watch for the missing parts to complete the Comet for a future project. For now I will be using the small Clinton on my Cheeftah with a centrifugal clutch.

I worked for a long time trying to remove the bolt holding the remaining parts of the Comet clutch on. The bolt is rounded so even a 6 point socket will not hold it. Tomorrow I will try a new socket and if that doesn't work I'll weld an old socket onto it.
I don't know if I can fix the tank.

I have have some removers like this.. they work great for removing damaged nuts and bolts

 

[sparkwizard]

I have good luck with a very small Snap On pipe wrench removing bolts like that. If that doesn't work, I weld a lugnut on it and wait for it to cool. That breaks the rust in the threads and I can usually remove it without tools.

@tomc
Does this look like the same tank?
If you think it's the same let me know. I know this engine is seized but tank might be usable, it's yours if you need it.

 

[tomc]

I finally got the bolt out, using a new 14mm impact socket. All the bolts in this engine have been tighter than necessary. I'm surprised the gorilla that worked on it before didn't break any tightening them.

I now have the engine down far enough to clean it for painting and probably clean the valves & seats before reassembly. I still have to remove the broken muffler from the exhaust port.

I believe that tank is bigger than mine, and sits up higher above the cylinder head.
Mine appears clean inside so I will try to repair the threads for the cap, or replace the "spout". Some patient work with pliers might get the threads back into shape.
Thanks though.

I tried fixing the filler spout with pliers. No success. So I used my MAP torch and unsoldered it. After less than minute of heat it fell off.
I have a good clean "lip" left to solder a new piece onto. I'm glad the tank is made with the raised portion to solder back to. Now I need to find a donor the right size.
Meanwhile the tank will be filled with Evaporust to clean the inside.
