G'day all
Just a quick note for the banter going on about what oil/fuel ratio is best.
I've written up some of my ideas on the best ratio for the issues we have to deal with on our 2-stroke Chinese Bicycle Motors.
I firmly (and with good supporting evidence as listed in previous post) use plain old 2-stroke mineral at 20:1.
Doing some research i came accross a castor oil fortified 2-stroke oil listing the oil/fuel ratios for various applications.
In the world of lubrication, nothing gets any better than straight degummed, first pressing castor oil for maximum tolerance to heat and pressure.
This product (similar to others) is a blend of castor and synthetic but when the going gets tough, it's the castor giving you the real protection.
Scroll down to the bottom of the page and look at the oil/fuel specifications.
Since our bicycle motors are air cooled and small capacity, they most closely fit the "Kart" specification.
My goodness, they recomend 20:1 and that's with the extra protection of castor oil.
Naturally, everyone will have their own opinion
Still, it's food for thought before you try and run your Chinese Bicycle Engine engine on 40:1 or worse, a nightmarish 50:1 just because the oil container says it is recomended for use at 50:1
