Ya i know but i got those numbers off the specs on the right hand side of the sheet.I dont know if those are actual from the guys who sold this(Gibbs Hobby& Reasearch)or its a speculation from a calc program or somthing but by looking at the sheet i dont think PC"S where in evryiones possesion either.Heres the rest of the readings in order,i only put a couple:
weight--6.5lbs
oil mix---32:1
Performance,Top Flight or Zinger prop:
18x10-7350
20x6-8050
20x8-7500
20x10-6500
22x8-7000
22x10-6000
The hobby was located in North Canton,Ohio.(Either its the 3 rings or the elevation.)maybe they modded or ported it somehow.At an oil mix of 32:1 with 3 rings i doubt there was any blowby.
Heres a quote thats in the center bottom of ad:
(after extensive testing, it has become evident to us that under normal conditions you will probably never wear the Kioritz engine out with a model aircraft).
