Customer Question

I have a 1936 20/25 Rolls Royce, 6 cylindre petrol. The engine starts fine, runs with the hand throttle set to quick, then after 2 minuites, dies off to a struggle, almost stall, then recovers and the same happens over and over. We have changed the Gaskets and Cork diaphragm in the Autovac Petrol Pump............ what else could it be, The coil maybe?

I'd agree that it would be wise to check over the state of the ignition system as I've known things like coils and plugs and leads to develop misfires as they heat up

so if you can find a new set of plugs and check the leads for high resistance as the 1st step
