Updated 10/10/06 – i’ve road tested it again and the noise starts once the engine has warmed up. The sound reduces when I close the air lever to make the fuel/air mixture rich. Altering the timing lever makes no appreciable difference to the sound which appears to be happening when the engine is under a slight load.

i’ve never heard a Scott engine ‘pink’ before but i’m thinking that’s what the problem is !
