There should be a slow running mixture screw on the vapouriser Dave.

You don't say but I'm assuming you are running a normal carb/mixer setup?

If it's multipoint injection, then I'm sure there's someone here that can advise.

As It ticks over on Petrol ok I assume it's only an lpg/mixture setting.

Hi Dave
I had a simmilar problem with my Winnebago Ford V8 , it wouldn't tick over and kept on cutting out on bends and islands , it ran fine on petrol .
Turned out it needed a new idle control valve nothing to do with the LPG convertion diagnosed and repaired by Duncan ( Starspangledspanner)

Hi Dave.

My carb is some 30 years old....so...I bit the bullet and have just installed a brand new one....

It was showing some signs of wear and I figured that if it helped the lpg conversion setup and running, and the fuel consumption it had to be a good investment.

BTW If you ever need and bits...especially exhaust pipes making to your specs and drawings...I can highly recommend Cliff @ Carolina Classics....

I sent him the drawing and he got it back within 3 days....BOUGHT THE SILENCER/MUFFLER AND GOT THE TAIL PIPE MADE UP TOO.

Now I am very impressed with that as everything has to be made to measure.Fits perfectly.:thumb:

VERY reasonable price too.You'll be surprised.

Hope you sort it.

Might well be worth talking to Duncan as Tony has mentioned as it is injected.

Steve.

hi steve , on reading your last post i dont think it would make any difference to running on lpg as you only use the throttle butterfly on a carb .should make the petrol running better , but do you use much petrol or stick with gas. cheers alan.
