hi guys , seen a few that look like the one i have bought it for $30 at a market . works perfectly tho i dont know what it is but same colour as a twin ? seen one and it was a monaro but mine has a black cowling tank at the rear g4 i think with idle adjuster and if the engine number is right ........... 108780 11 . but some bad stamping! Any info would be great but its ok if none . thanks Dave
