ASA ruling on performance pellets

[Tony Press]

My first 1929 Saloon was very original and the engine was untouched in 1956, so it was burning oil at some rate leaving a good plume of smoke. I heard if this spark trick so added a short Meccano strip at the plug and connected the plug lead with a spark gap. This worked well until an overhaul. 

It looked like a fireworks display under the bonnet in the evening !
