I removed my 33cc 2 stroke tran's

Takes a 70mm clutch or whatever I guess.

I'll get a picture of the other sides but as you can imagine theres a clutch drum, and then clutch shoe assembly in the keyang engine.

How can I get a clutch assembly like that, that'd fit this trans? I was thinking of using my old trans till I can afford the 4G

Edit: Googling I found the engine w/trans removed.

There's 2 different PTO shafts on the HS. One has a longer keyed shaft, and the other has an arrangement like your engine, a short tapered shaft.
The tapered shaft engines take different transmissions than the long keyed shaft versions. There are 2 diff kinds of 4G because of this - one a 76/78.

Only info I can find on your clutch is this: http://www.vizamotors.com/clutch-assembly-keyang-33cc-p-477.html

It doesn't list the diameter, so you'd have to measure the clutch drum diameter to find out what size it is.
The 2 most common sizes for that type are 52/54MM and 76/78MM. Measure your drum and if it's about 3", it's a 76/78.

Yeah thats the clutch.

The drum (& clutch) are bout 3' 1/4th it seems so probably 78MM ?

Now I was thinking there was 2 shafts, what does the 4G belt trans use, the longer keyed shaft right?

I wanted to use this trans to save time/money I wont beable to afford the 4G belt kit till summer ish, however I can almost right now buy
