OK, silly things first...do you have good connections between motor and CDI?
Get rid of the kill switch.
Make sure the fuel petcock is on (pointing in the same direction as the fuel line.
Press the button on the carb to let the fuel in.
Pull the choke all the way up.
Do not give it gas while the choke is on.
Once it fires up, pull in the clutch and stop moving....close the choke all the way...let the motor warm up before you start revving it up.
Take the idle screw, turn it all the way in (just until it stops - NOT TIGHT) then back it out 4 full turns. Out further slows down the idle, in speeds it up.
I know you checked the spark, and have fresh gas...that just leaves compression - which I'm assuming is there, and air/fuel mix. I don't know how the air is in Oregon, but maybe some of the guys from out West can tell you where the e-clip on the carb needle should go.
****, look at me - computer guy trying to help someone get a motor running! Who'd thunk that would ever happen???
Good luck, and keep up posted...what I listed are what I think "basic" things for troubleshooting.
