hello there i have a single point lpg system on my car and im trying to get the basic tuning right i was wondering if anyone here would be able to give me any advice on how to tune the zavoli vapouriser DMG51530GPL,its got 1 small screw by the water outlet a very big screw on the front of the vapousiser and a restrictor adjustment in the main feed tube just before the mixer

It's a pretty long processes. The best way is to get an exhaust gas analyser or lambda sensor.

You're use the small screw to set the idle mixture, the big screw for running mixture, and I can't quite remember what the big stopper thing is for. I think that's flat out mixture compensation or something.
