LPG Stalls on braking

[PG]

Hi to all, I've just picked up my second LPG vehicle, and it runs fine on
petrol, but when it comes to running on LPG, it is good on long journeys,
but round town, it seems to stall whenever you let it idle or apply the
brakes, for instance, at traffic lights. It's over 2 weeks until the LPG
specialist I use can look at it, so I thought I'd have a look around for
some tips.

Thanks in advance

this happens when the ga/air mixture is too lean or strong. since it
is present when you apply brakes, i suspect it to be too too lean.
The LPG regulator (the cylindrical unit fitted in engine compartment)
has a screw to tune the amount of gas released in idle speed. it is
located near the horse that is fitted to your gas/air mixture.
(remember in some systems there are two tuning screws, one for idle
speed and one for sensitivity. make sure you do not turn your
sensitivity screw, as it might cause troubles in high RPM as well.
most of the time idle screw is more accessible than the sensitivity
screw).

before rotating the screw make sure you can reset it to the current
position in case you need. try adjusting the screw until you get a
smooth idle speed.

Horse? Is that in case the vehicle breaks down completely? :-)

I am assuming that the system is a single point unit. It might be
worth checking to see if you have forced ram induction coming from the
air inlet, as once you come off the throttle, the air is forced down
the inlet pipe, making the engine go that lean that it cuts out.
