Hi all,

Advice needed please, My mc16 recently acquired is running fine at tick over but really runs rough between 2 and 7 thou and stutters like mad before the power comes in . I've cleaned the carbs as it was only running on one pot and the power valves appear to be in sync .
I know it could be any one of numerous causes but any suggestions would be greatly appreciated as i'm new to resto's and my two stroke knowledge is passable but i'm no mechanic.

Ps has anyone used Firefox racing in keithley , Yorkshire. just curious as thinking of using them to rebuild a spare engine i purchased for the bike.

Thanks in advance
Brian
