fueling problem!

[REBEL GT TURBO]

right my mates gt turbo is having problems, its got the standard t2 turbo, group a fuel pump, new fuel regulator and filter, its running 8 psi standard boost ive fitted my afr meter to it and its reading 14 which is too high also when on boost its not dropping down its going up to 15/16 and the turbo is stalling! Fuel is getting though ok ive checked that also cleaned the carb out and cleaned the small fuel filter but its still doing it? I had the same problem with mine which turned out to be a badly built carb! This carb is standard and has been serviced 2 months ago. Any sugestions? Shouldnt need a bigger jet when running 8psi?
Thanks guys.

just tested it again now after messing about and its running very lean? 14.5 on afr! What else can i check for guys? Im out of ideas! Need to get it sorted for tomorrow if poss!

Thanks.

also fuel pump is fine just checked it on my car!

any air leaks ?, maybe worth takign the carb off and putting a small amount of sealant aroudn the carb base incase its leaking slightly there.

[REBEL GT TURBO]

also there is a small boost leak from the carb but that would just cause it to run richer anyway right? The leak is caused by the choke flap spindle.

its running lean at normal and then even leaner when boost comes inn!

[REBEL GT TURBO]

Anybody??:confused:

[youngscottie]

You say running lean at normal what do you mean by this?
Idle/light or part throttle
Mines will quite happily sit in the 15/16s on light throttle
Mid 14s at idle

From what I can gather from the above statement it may just
Be your wot that's the problem

But I could be way off the mark

when its on my car its on 12.2 when boost kicks inn it drops to 11.5 it should go down because more fuel is chucked in on boost, Im sure anything over 13ish is lean 15/16 is very lean and can cause detonation!!

Normal as in not on boost just low rpm.

he took it onto the motorway and floored it and it went round to 17 in the red!! its sitting 1n the mid 14's amber on idle.

Somethings wrong it was running fine the other nite now its doing this:confused:

[REBEL GT TURBO]

is there any other components other than fuel pump, fuel filter, fuel regulator and carb jets that control fuel/air mixture??

its running a straight though exhaust and just a trumpet as the intake no filter, so its getting shat loads of air...its as if the fuels not getting inn quick enough?? sometimes it holds at 14 even in boost but never drops when on boost! we changed the fuel filter and regulator tonight and thats not done anything! :scratch::scratch::scratch:

[REBEL GT TURBO]

its also doing some (mega backfire) when in 2nd as you boot it...sounds good but im sure its fuel starvation!!

Awwww have i hurt there feelings?? haha :laugh:

If all these probs started after the carb was touched
Then there's a fair chance that's your prob

You idle and part don't need to be as rich as 12s
At wot I like to see low 12s

I'm no carb guru if I were you I'd strip and clean it for a start
Sort your air leak when your there

[car.crash]

I doubt it, but your pals car is running like crap and the guys with the knowledge won't help after your rant at them.
