Re: opti-2 I'm sold on it.
steve: it is great stuff but 100:1 is only approx. 1.25 ounces of oil per gallon. personally, i wouldn't chance that minimal mixture with these chinese motors and their loss tolerances, and entry-level components. it might live on 50:1 but 100:1? and the bloke at the shop is not correct about 100:1 being ideal for all 2-strokes. even outboard motors with oil injection vary the mixture. is approx. 100:1 at idle, 50:1 at cruise, and as low as 32:1 at full load/throttle. IMHO
