the furthest back is fuel feed, then the fuel over flow and last the oil breather

[lrostoke]

theres a picture somewhere but most likey


bottom pipe near bulkhead is fuel inlet, pipe above that is breather/overflow

then a larger pipe top and front is engine breather pipe.

Picture found



4= fuel inlet

5 = overflow/breather

6 = engine breather connection

7 = mixture screw

Daft question, does the engine breather connection need to be connected as it has a bolt jublee cliped insed it????????

The engine breather pipe should be connected as it creates a partial vacuum in the crank-case, helping to keep it clean & reducing the chance of oil leaks, most importantly from the primary gear bushes which, by design, cannot have an oil seal.

Great picture/explanation there IRO. And yes - the breather MUST be connected if you don't want oil leaks!

[lrostoke]

Can't take credit for the picture I knew there were a few about the questions been asked often enough, I google imaged

Save & use them as often as you wish

I don't know about the UK, but in germany breather filters are verboten since 1974!
Resp. it's illegal to 'dump' crankcase fumes in the air. They must be burned off.

Im not sure if im being thick , but were does the breather go on to???
Thanks all of you for you help
