Hi I have a 1974 dual solex PDSIT 2/3 carb, 1800cc, from USA and I'm currently trying to set the accelerator pump volume. Haynes says: 1974 (valve open) 0.55 - 0.85 cc 1974 (valve closed) 1.3 - 1.7 cc per pump stroke. What valve is Haynes talking about? I see section 14.9 says: In late 73, on the 1.8 litre engine a valve has been fitted ... (paraphrasing...) ... below 21C it's closed and pump delivers 1.5cc, then above 21C the valve opens and allows some of fuel to go back to float chamber roughly having the delivery volume 0.7cc. Anyone know where this valve is? If I don't have it, do I just set to 1.5cc ? Finally, is 21C the air temp? Many thanks Ian
