ha ha, thanks for replies. I have a Rover Suzuki mower that is currently playing up and just picked up a old Victa Hawk 2 stroke that is going but the carb is leaking.
I normally run 98ULP in my bike and on the rare occasion some AVGAS. But I would not run AVGAS in my Lawnmower! Grumpy you are correct about the Castor, it does not mix well with AVGAS but never had any problems with 98ULP. I have used Castor oil for years in my race bikes and always had great results.
This is often a topic on which 2 stroke is better, Castor or Full Synthetic.
