my car has been using a s**t of LPG lately (28+Lts / 100km)...

so finally i checked the mixtures....its idling at around 10:1, and not going better than 12.5:1 on power, cruising at around 11:1..

ive adjusted the idle and power screws to try to lean it out...the idle refuses to improve no matter what and now under full power the mixture starts at 13:1 at low revs and leans out to 20:1 at max revs...

so what the frig is goin on with this bastard....the way it is is ridicules
