On mine there is a fitting in the gas line to the air intake. It is a fine threaded fitting with a screwdriver slot in it and a lock nut. About 3/4 AF. Loosen the locknut then screw the fitting in or out. Screwing it in makes the mixture weaker. Try half a turn at a time and see how it goes. Nip up the locknut when finished.

There should also be a screw in the convertor which adjusts idle mixture.

Dont lean out the lpg mixture too much, particularly with the adjustor in the vapor line - a lean lpg mixture can result in engine damage.

Its best adjusted on a dyno with a CO sensor in the tailpipe to achieve the correct mixture under load.

The only way to do it properly.

The other way is to fiddle with it & hope its ok,but could be to lean & you wont know until the valves are burnt.

And before it goes on the dyno make sure you have a new air filter fitted & no manifold leaks.
