[NSRCA-discussion] OS160 Longevity

[Terry Brox]

Vicente,
        Castor does not hurt the diaphram in YS's. It is the petroleum based products that do. Castor is not ran in YS because it carbons up worse. The higher heat of a 4 stroke, and castor can carbon up everything for the exhaust valve to the tuned pipe, and everthing in between. It does make things more forgiving to lean runs, as castor usually has a higher flash point than synthetics. If I am wrong here, maybe Troy can chime in on the whatnots of YS's. He has a lot of experience with YS and fuels of all types. Terry

  What is the effect of castor oil on the pump diafragm?  I understood that we can not use Castor oil in YS because of the diaframs and regulators parts.  I am not sure now if castor oil couls cause similar problems in OS 140 RX pump and the and the Perry pump.
