Hello My mk2 has run rough and rich since I bought it so I decided it’s time to adjust the mixture the mixture screw on the intake doesn’t seem to change the idle speed much if at all and I’m now looking at the mixture screw on the metering head. the 3mm Allen is completely rounded and won’t budge so can I adjust the mixture by turning the whole bolt instead? thanks
thats not your mixture screw. have a read: https://clubgti.com/forums/index.ph...air-and-tune-your-mk2-corrado-1-8-16v.195423/
