Mk1 Concentric Carb
« on: August 19, 2013, 03:30:21 pm »
Hi Folks

I have a Mk1 Concentric on a Sixty 5, the bike appears to be running a little lean, and I am going to try turning the air screw an eighth turn to see if that improves the mix. Is it a clockwise or anticlockwise turn to reduce the air ?

Thanks guys (and guyesses) Live Long and Prosper
Oh, what sad times are these when passing ruffians can say Ni at will to old ladies. There is a pestilence upon this land, nothing is sacred. Even those who arrange and design shrubberies are under considerable economic stress in this period in history.

Clockwise leans it. You want to go counterclockwise for rich.  ERC
