dual fuel xf chewing petrol

Hey people.

I have a question about my xf which is on gas. It's a carby and I have been told by the mechanics that the carby needs a overhaul to run properly. When I do run it on petrol it is way to rich and chews through the petrol and will not idle.

I was wondering if the fuel mixture and air settings on the carby affect the way the gas system works. The gas gets fed to the engine through the carby so i am unsure wether the carby settings will muck up the gas tuning.

Also would a faulty map sensor stuff up the petrol settings?

Thanks guys!

Re: dual fuel xf chewing petrol

nop the map sensor on the cf carbys will only affect igniton timing.. THe fuel settings will have a very minor affect on gas idle speed and nothing more. The gas dries out all the gaskets, then when there finially used it leaks through the gaskets usually the power valve one is the usualy culprit to cause black smoke

Considering you live in Melbourne, have you considered removing the carby and running the car on straight gas?
It'll run better, perform better and probably be more economical than on dual fuel.

And you wont have the problem of the carby drying out as INJECTED suggested.
