johnson 3.3hp outboard 2-stroke q's

Hi there,

Was helping a friend for a few mins with a johnson 3.3hp 2-stroke he bought from a consignment store. He has no idea what its history is.. but the motor was manufactured 11/98, and while the cover looks faded.. the motor itself looks pretty good.

I've read these are re-badged tohatsu motors and that they are very reliable..

Anyway, we troubleshoot(ed) as follows:
- check fuel lines
- new fuel and oil 50:1
- new spark plug
- new ignition wire
- checked for spark.. OK
- compression check.. OK

The kill switch is broken.. so we clipped the two wires running then and stripped them to expose the wire. I suspect that connecting the wires would short the motor and kill it.. but we tried starting the motor with the wires in both connected and disconnected configurations.. nothing

It has just the forward gear and the prop spun freely when pulling the cord.. it wouldn't fire though..

I don't really know what else to suggest.. or try. If anyone could suggest the next few steps I would appreciate it. I suspect it must be the carb.. but confirmation from someone who knows the motor and/or outboard in general would be appreciated!

Thank you
