I have a 68 Mk1 on strombergs. I run the car on unleaded with Castrol Valvemaster as an additive. I recently refurbished the carbs. Does anybody know what CO figure it should read when analyzed? I got it to read 1.5 % but the car hesitates at 50 -55mph unless I use partial choke. It also runs on when the ignition is turned off, what should I set the timing to when using unleaded?
