Threaded, at least mine are.
Hi Paul,... what's best non-destructive way to remove or rotate just the spraybar ?....there's always been lively discussions on spraybar # of holes & orientation direction for optimizing fuel atomization issues from way back i was flying Fox nitro airplane 35 & 36x motors.
Hmm...my spraybar has a venturi centered, 90° thru-hole pointing straight outward & inward ....maybe a production change ?
