The smaller screws under the centre round cap are your idle jets, what are these, theyll say something like 45F9
On the body tubes, up near the butterfly plates will be a approx 1cm round screw in plug with a screwdriver slot, undo, and pull out tje 4 cm long with a thick bit in the middle, these are your pump jets, theyll have like 50 on them, what afe yours?
Next inside the centre bore main tube, ie the 45 mm diameter bore, halfway down, are rhe Auxilliary venturi, held in by a screw underneath, it will be something like 3.5 . Whats your?
Behind this is the choke, it is a narrowing venturi, no need to remove, you will see a figure, like 36. What is yours?
What are your cam opening and closing degrees, ie how much overlap do you have?
And is your engine a stock L 18 at stock capacity?
Are you running twin webets or a single?
Lots of questions, but the webwr documentation will give an indication of what you could aim for.
A decent air fuel sensor and wide band display, with car running under load, will help a lot.
Or
Yeah, a tuning shop! Whats your suburb/location, there may be some on hete that could guide ypu towards a shop more suited.
