Good evening all
Tried starting 1256 engine for the 1st time in over 4 years, but gave up after a couple of minutes due to petrol leaking from the bottom of both carbs. (Brabham carbs and manifold)
Think they are early cd150s as they have smooth brass finish to the bottom, (not Castle type nut).
I read a thread from around 2 years ago saying possible O ring failure.
If i purchase 2 rebuild kits from ebay £17, I assume they will have the correct O rings.
My question is??? if the piston and diaphram are removed is it possible to replace the O rings from the top or will the bottom require removal to replace the O ring,
Any help gratefully received
Regards Ian
