Fifi has the 281f carb with a mixture screw near the base. When she first arrived I had a bit of a pop pop pop on overrun so adjusted the carb as per Hayned, IE screwed it completely home then out 3 turns and voila no more pop pops. Strangely this has started again and I have had to screw the jet out another one and a half turns to stop it. I checked the timing and points gap and all was spot on. My question is, does screwing the jet out richen or weaken the mixture? The controle technique is due next month and they tend to be keen on emissions, my intension is to weaken it on the day as much as I can (everybody does that here if they can) and still let it run but do not know which way to turn it to weaken it.
