I've just about finished fitting my m50 manifold but I have found that when pressing the throttle all the way down the throttle plate doesn't fully open.

If I adjust the cable so that it does open fully it then doesn't return to fully closed (idle) by the same amount.

Is there a method to properly adjusting this? I don't want to improve the airflow with the manifold and then be robbed by not having a wot.

Whilst out today I think I've worked it out. I think I have to pop off one of the ball and socket jounts and adjust the difference with that rod.
I'll give it a try and post up what I find.

Which throttle body are you using, m52 or m50?

The ball type joints are not adjustable, if you twist them they will break.
You adjust it on the threaded outer, really simple, maybe you have something missing?

If anyone else is ever having a similar brain fail, it was simples I adjusted the stop beneath the accelerator pedal.

Just seen the replies after I replied. Thanks for the replies.

I used the m50 throttle body, I had it adjusted on the threaded part of the cable that comes through the grommet on the throttle body bracket. There just wasn't enough travel on the accelerator pedal itself.

I loosened the 13mm nut on the pedal stop and threaded it in until I could get WOT, then I adjusted it back up so that it would stop the pedal as soon as it reached full open.
