Countersunk Screw
Help!
In process of doing 200 hrs service 912ULS
In situ inspection of carburettors.
Done - idle jet adjustment, float chamber, fuel level & float weight.
Started to remove top chamber, to inspect diaphragm, jet needle, etc - front Phillips head screw undid without any issue. Rear solid, applied pressure, starr rounded out.
Countersunk screw, PN. 841341 M5 x 12 - assume stainless steel. Anyone know the thread pitch?
Any suggestions, short of removing carby ?
😈
