Forty Featherweight with Bing carb, see below
Silver Century Plus
Above is the tech details on these engines, click to display
(Please note the forty Featherweight shown here is fitted with a Bing carb. The majority of early forty models were fitted with Villiers carbs. Bing were fitted for just a short while when Villiers were not available. In later years, 1980's, the Amal 416 was fitted.)
The two pages of an advert above have been kindly sent to me by Mike Merker, I had not seen this advert before, if you look closely at the address, you will see why!
The three leaflets above sent in by Dave Barker, thanks Dave.
Nice finish on these motors Myles! the Silver Century again. One point I would like to make is the position of the float chamber. British Seagull stated it was important to fit it furthest away from the tank, not as here. Now I cannot see the difference it makes, except that the choke assembly fits snugly into the float if fitted as British Seagull suggest, and the choke flap is somewhat protected too. As Myles points out however it might be better the other way round to prevent the fuel evaporating with excess heat from the head? Not a problem in UK, but in warmer climes maybe....
This picture was sent in by Magnus in Sweden, it is one of the last ever engines to be built. A 'Classic 2'. It was a featherweight with all the bells and whistles! Twist grip throttle, water injected exhaust and all. Note the gold top. That is how they left the factory. Apparently it is almost unused.
This Motor, a WSPCL, is unused and in as good condition as the day it left the factory, about 30 years ago. Owned by Mathias Hedstom in Sweden, he has bought it to use it, for the next 30 years if he looks after it, what a nice find!
