TOYOTA 42-7FGF25 LPG PROBLEM

Serial number...15777
Year of Manufacture...2004

I need some information if anyone can help with the initial settings for the LPG fuel system.
I am looking for the initial settings for the :-

1...Gas carb main jet adjustment ( How many turns out )
2...Throttle stop screw adjustment on the vacuum unit
3...Aisan gas unit mixture adjustment screw ( How many turns out )
The accelerator is fly by wire.

I Have the settings for the Aisan systems for the Hyster trucks but they are not the same.

Thanks Friends

Hi Steve,
We are not having problems with the accelerator system.
I need the factory settings for the carb main jet adjustment screw, gas unit adjustment screw and the anti stall adjustment screw.
There should be factory settings for these prior to fine adjustment when the engine is running.
The problem is a so called service engineer ( car mechanic ) has been given a screwdriver for his birthday and screwed up the settings completely.
We have all the settings for the Hyster Aisin systems which is similar to the Toyota but not completely the same if you get my drift.

Cheers

Micky

Mickey, Fly by wire. I don't have the settings- what type of problem are you having?
