pooberg set up.

Right I have stripped and rebuilt my 2e using all new gasket o rings and the like. 
Auto choke is working, as I didn't before.
The slidey push out thing does what it should on the left of the carb.
Waxstat works and has been tested, all electrics to the carb work.
Now I would like to set the co2 mixture as cannot remember how many turns it was at me for I removed it.
Also is there a mixture screw as it's running very rich?

This is all that's stopping me getting it out on the road, so any help would be most awesome.

Thanks

To set the co you really need to do it on a meter like what they use on your mot

Without this you woukd just be guessing

Hi
The Co2 mixture is the mixture screw, if its running rich its probably that.
I always set my mixture by ear, if you have a reasonable tick over to start then just wind it in till it runs lumpy then wind it back out until it again runs lumpy then just wind in till you get a sweet spot.
If you get it so its running nice you can then check your spark plugs to see how close you are,black and oily to rich, nice light biege/brown and your spot on
