Hello all

I have cleaned this engine up. Serviced the ignition, carby, decoked all carbon, fresh oil & valve gaps are OK.

The engine starts easily and purrs like a kitten on idle.

As soon as I increase revs it starts missing and pumping what I believe is petrol smoke out the exhaust.

I am after some idea's as to what I could try next. Thanks in advance from Mark.
