Hello Prentice.

Thank you very much for your advice, it was condensation within the distributor. A good drying out with an hot air gun as done the trick.

I must say I was sceptical about condensation within the distributor, but you were certainly spot on.

The only problem is I have had to weld up the silencer (muffler), all the cranking over with the gas on and the associated bangs has split the silencer box. As an aside, I would have thought there should be some protection against a build up of gas within the system should start up not take place.

However, again many thanks.

Regards

John Taylor
