 Ken I screwed up on reporting the  rotor slot width, it s= hould be 2.17 to 2.26mm not 2.017 to 2.026mm

Georges,
    Are these numbers in reference to the apex seal s= lot taper from
the bottom of slot (2.017 mm) to the top of slot (2.026 mm) which
is a taper of (.009 mm) or about 3.54 thousands here in the 48 = ??

Correction, the readings were 2.017 to 2.026mm

 Hi! Ken
Do you you cut on a taper, where does your taper start? or do you ju= st skim 0.015" off each side for a total of 0.030". I just measured the t= wo rotors that were in a "GOOD" running 92 13b NA & got a reading of = 0.017 to 0.026mm, I guess they are toast.
