Actually you can use Caster bean oil. That is about as close as you can get to salad oil. You can still get it at a motorcycle dealer that sells racing oil, there are some that still claim that it is the best oil for the 2 stroke, if you try, run it at 30:1. It is all we would use in our Hodaka's, always had good luck. That was a few moons ago. Have fun, Dave
PS: I love the smell of caster bean oil in the morning, smells like racing.
I have some bean in a spray can, I put it in the Whizzer gas just for the smell, top oil! Grandma used it to clean you out, we needed to stay away from her house when she got in that mood. Rest her soul she meant well. Have fun, Dave
Ascot Park, Saturday night 1/2 mile flat trackers, those were the days, the smell of the bean in the air. Takes me back, Sammy Tanner, Bart Markel my heroes.
Actually, if you want a real clean burn with out the blue smoke, use the white lightning, Cohlman lamp fuel and Castor oil mix well with no smoke and a very hot fuel mixture. To even add more to it, add an once of 20% R/C Nitro fuel.
It will be like running top fuel methane in your gogo machine. 8-0
