Does anyone know the initial carb settings for the 440 Xen. liquid motor. Air screw, Idle screw.

I will look for them at home but if I remember they have the float bowl with the adjustable MJ?
It was the cause of many burn downs because the MJ points up in the bowl and can draw air. Use plan 38 float bowls are much better.

Any luck Toydoc?

Not yet.
I think the air was 1.5 then set the idle with uni-sync.
