That's awesome dude cheers. Should I solder it up and drill it to 1.0mm first or just go for 1.2mm straight away?
I think it's a 1.2mm

Make the air corrector bigger or make the main jet smaller. In my experiences they can both make a big difference to on boost fuelling.
Cheers buddy sorry I didn't see that post till just now.

Drilled the 0.9mm to 1.0mm and that took the AFR from high 10's to low 11's my next drill is 1.2mm will that take it too far?

If the last 0.1mm step is anything to go by that should put me in mid to high 11's! :wink:

Found this very helpful for removing the AC jet. Maybe helpful for you guys too.



3mm ID boost hose, screwdriver and a bit of moisture to seal the air in. Worked for removing and installing once loosened with a small flat head.

Genius.

It's been a while since I took my carb apart, but isn't that the small jet that (assuming the carb is still fitted to the manifold) that can drop into the manifold and really ruin your day?

I think I remember not having the balls to change mine whilst the carb was still fitted.  :lol:
