Default Saw engine on bicycle

I found this really wierd saw in a dumpster it's like a chainsaw only it has a belt going from the engine to a pully attached to a circular blade but i only took the engine part. I was thinking about ataching it to a bicycle, so my questions are as follows:
1. Where can i get a pully and how can I attach it to the wheel?
2. What ratio do i need? The clutch has a working diamiter of ~ 1.5 in. Would I need a smaller wheel so the engine could push it?
3. How would I attach it to the bike?
4. How can I hook up the throttle so I don't have to be controlling it from right at the enigne. Like a throttle grip or something.

Extra Notes:
The engine's rpm is 5100. Pics tomorrow probably.
Thanks!

Any chainsaw over 60cc is worth more than a motor designed for cart use.

Well from my short experience in adapting chainsaws.. you can't just buy a part and plug it on. A pulley will probably require modifying to fit on.. maybe threaded, maybe keyways cut - it all depends on how the saw is.

Anyway, go for it if you can! I'm in the process of attaching my 100cc chainsaw to my bike!

3. Make a a mount for the saw, attach rods of metal from the mount to your bike..
4. Well thew ay I'm doing it is hooking it up to my rear brake.

The chainsaw already has the pully on it all i need is to put the pulley on to the back wheel.
Also it won't start up for me only my friend could get it started and I don't how he did it.

He's got the magic touch or it doesn't like you.

Whew... got it running
Attaching it to the bike might be a problem cuz i dont have any metal working tools my friend might though..
also what about the pulley?
The engines kind of big so u guys think i n the middle or above the rear wheel my friend said i could try putting the pully on the pedals so it just moves the bike chain and can shift gears and stuff.
Thanks guys!

A custom pedal shaft so it could shift would be freakin sweet.

just mount the engine where the pulley on the engine is pushed down on the rear wheel and make it a friction drive?
