I'm looking to fit a new metering head to my rst at the weekend as the one i have currently is faulty
Have any of you guys got any tips for fitting it and then getting the car running so i can fine tune the air/fuel mix??
any hints/tips welcome peeps so fire away

The RST supplement of the Ford's workshop manual covers it pretty well. Have a look there.

As a general rule, i personally, would:

1. Fit it.......
2. Before you adjust anything see if the car starts.........
3. IF it does....
4. Get it (as a BARE MINIMUM) on a CO analyser ASAP and DON'T boost it up
5. If it doesn't........check for fuel at the injectors with the pump running, and if it does that try adjusting the mixture screw fractionally until you can get it to start and then go to 4.

i looked in the workshop manuals i have and there not much help i'm gonna look through me haynes 2moro so maybe more luck there
Cheers safechav i was thinking along them lines, my mate has a sensor(closed loop lambda i think he said) to setup the air/fuel but the thing has to start up first i just hope the new metering head hasn't bean messed with much!

Chris69

Is there like a set position, maybe a number of turns clockwise or anti-clockwise that i can turn the adjuster to set it up at a standard level just as a base?? before i fine tune it of course

SafeChav

Not that im aware of myself. Just try and see if it starts mate. When i first did the cabby i had a fucked metering head that was overfuelling a cylinder and that started pretty much first time, it backfired like a slag aswell

Chris69

should be fun then

JesseT

Are you reallly sure you looked in the S1/S2 workshop manual. There's dozens of pages of how to set up the metering unit including the base levels.

Chris69

i had a look at the manuals i have and i just covers the basics, sounds like u have a more in depth manual than the one i've been scanning through
thats the manual i have in ur link i can't find wot u mentioned though

SafeChav

I downloaded that manual aswell and i couldnt see a lot helpful in there unless your considering removing the engine

SO.............have you done it yet Should be running by now takes half hour tops to change a metering head

Chris69

i'm doing it 2moro
its not the fitting it, its the booking time with the person whos gonna set it up for me
i'm rolling about with 5psi at the mo just to be on the safe side- my xr3i rules

SafeChav

So..................whats wrong with your one now then if the car starts and runs

I would be VERY surprised if the metering head is fauly

Chris69

to cut a long story short its not faulty as such, more damaged i spose- the fuel/air mixture screw(allen key) no longer works
the car runs fine at low boost(maybe a little bit lean) but i wanna up the psi a bit so i need to alter the fueling in order to not lean out etc
hence the replacement

SafeChav

Ahhhhhhh what a fucker. I had one with a rounded out screw aswell

Never a good sign either if you think about it

Chris69

I did think that but its had a replacement engine and a few fueling problems since i bought it to do with blockages so that little screw has been working overtime this year- shame on me for not replacing it sooner

JesseT

Had a look myself, and indeed the S2 manual has nothing very interesting, but have a look in the S1 manual instead.

Chris69

all done
i was sweating it a bit as it took the metering head a while to flow properly and adjusting it to start was a nightmare
now running a solid 10psi and a big smile on me face
