Quick,

Dist:
If you have your initinal @ 19 then leave the vac advance unplugged for now.

You posted you have 18 degrees of mech adv so that is good if your at about 37 total.

Start up and shut off okay?

What RPM does it all your advance come in by?

Okay the Carb:

You have an 830...okay

You need a 50cc spring & housing to run a 50cc pump set up so you don't have enough parts.

You have a #218 cam and I have one here too....it appears almost white or slightly green.

If you have the Pink #330 cam try them as they will produce the most cc's per shot.

Green is the next one down from the pink.

Your plug looks slightly lean but you need to go out and put some miles on them to color up.
