Stihl 039 tuning

[landrover 101]

have a stihl 039 that is a bit gutless so will be doing a muffler mod but which way does the high speed screw on the carb go to richen it up a little after it is done - does it want screwing in or out to richen it up a little

Other than being gutless it is an otherwise fine saw plug is the right colour starts and runs fine compression is good etc - just that the 025 i have with a modded muffler on it cuts way better
