-Replaced air corrector jet from 125 to 100

...and guess what? My issue running always very rich with no load (boost) is at last solved!

After letting it warm up, I've adjusted the mixture and the engine runs at AFR 14.7 at idle and 14.5 at 2500 RPM !!!!!

Now I can focus on adjusting fueling on boost with my extra injector driven by Megasquirt...

Thank you so much all you guys for the excellent advice and guiding
thats good to hear mate

what boost are you going to be running? as if your running an increase in boost then you will certainly need to drill the 2nd stage out to 1.2mm to start then if more fuel is still needed try 1.3
