2 speed, how does it work?
Yes, you'll need a clutch with 2 sets of teeth on it.
You'll have two chains from your clutch to your jackshaft. One chain will go around the 1-way sprocket, and the other will go to the 2-speed clutch. When the one-way sprocket reaches a certain speed, the centrifugal mechanism in the 2-speed will engage and overtake control of the jackshaft.
Here's the engine clutch you'll need. There are different companies that make this clutch, including Comet if you can find them

I guess I am thinking backwards but I was thinking the big one way gear would be a top speed but as it is supposed to work, the 13 tooth or whatever secondary clutch is a higher gear ratio compared to the 18-20 or whatever the one way gear is.
takes off with the one way larger gear and then as rpm's increase it slings the jackshaft clutch/smaller gear into play which spins the jackshaft fast enough to make the one way gear freewheel. correct?
edit, after looking at the clutch picture, both gears are locked together and engage with the clutch, still confused as how the jackshaft works then.

The big gear is your low gear ratio for take off, when the jackshaft clutch spins fast enough to engage the clutch bell (same as on the engine) the bell will turn and then Yes kick out the big gear into free wheel mode.. If you can find the right springs for the jackshaft clutch you could change the rpm that it shifts into high gear... If memory serves me right it's a 2:1 ratio with the free wheel gear being double the teeth as the js clutch.. 24/12 so if you have a 72 tooth rear wheel sprocket 1st gear would be 12:1 and second gear would be 6:1....
Here's the clutch I just got for mine.....

you say that. but I looked and looked and finally bought from the other source yesterday. I personally find the OldMiniBikes search engine futile and it usually throws up the whole inventory no matter what I am searching for. I even cut and pasted the clutch name and it didnt show up, so I had to shop elsewhere, dont like it, but I did.
