Looks like I'll be monkeying about with it some more at the weekend. Worried by Rev's ideas about compression, as it had been getting v.v. hot before it arrived at my gaff. Ho-hum.
With any luck I'm talking rubbish and it's something much simpler, it's just I've had problems with running for any length of time and starting in the first place as a result of valve problems. Hopefully it's something simpler. On the subject I'm finally getting off my a*se and am in the process of deciding what I need to order to get the Imp running right, I'm just about to order a new head and cam from Reg Patten engines, but that's another story!
