Although Alfred Angas Scott himself used them in some of his TT engines, I have never quite understood how they can really be of much benefit, as although the primary ( crankcase ) compression is increased, surely it also reduces the volume of the petrol/air mixture that is being pumped through the crankcase ? And the greater the volume of mixture we can get pumped up into the cylinders the more power we will get ? Perhaps someone will now tell us that the flow through the crankcase will speed up due to the higher pressure invoved, and thereby increase the volume at the same time, but I need convincing.
I have in the past bought three Scotts with stuffing blocks fitted, was never happy with them, and removed them. At least two pairs are still sat somewhere in a box in my workshop. If anyone wants them they can have them for the price of the postage and packing….
