hello folks, i pulled out that screw (no 41 in diagram below) with the spring on off my dellorto sha14 and i have no idea how far it should go back in. i cant start the engine so i cant tune the screw.its starts for less than a second.then stalls.the plug is wet. do i turn it clockwise? its confusing as in the diagram it is not a normal mixture screw that restricts a channel. it seems to act as a stop for the plate.i cant understand the function of this 2 part plate with a big spring.
