Saving Old Seagulls

i have a WSPC (amal carb) silver century with a cracked block. i dont have a spare amal block but do have a couple of W(villiers carb) blocks and some spare villiers carbs.can i simply substitute the block and carb(effectively turning it into a WPC)or will i need to retain the rod ,crank and/or case from the W century?i read somewhere that they had a slightly longer stroke(theWSPC) so i guess something has to be different. would appreciate any help please
cheers

No problem, this is a straight swap. Naturally the Amal carb and the Villiers carb aren't interchangeable because of the inlet stub.

thanks charles. almost sounds too easy. so the strokes are the same then? or doesnt it matter?

Yes, the stroke is the same. The crankshaft, con-rod, piston, all the same.

You may of course need to change the throttle lever.

ok.thanks again. excellent news! got a few villiers cables no amal ones in good condition.this motor is going to drive my new boat a treat!
