I am going to be rebuilding my carburetors as soon as the rebuild kit gets here from victoria british, and I wanted to sync the carburetors and set the air/fuel ratio. I found a guide on the internet pertaining to the L18 engine, and it says that for my climate (70 degrees farenheight), the a/f **** on the bottom of the carburetors need to be turned out 1 1/2 to 2 turns. Is this the same for the L24, or is it more/less?
