In the (gas engine,glow fuel,no ignition thread) its stated the formula is:
a)-car or plane fuel 10% nitro---10% oil--oil is the keyword here.1 gallon
b)-regular gas------------2 gallons.
This is all the ingredients.your running 18% oil as stated in your opening post.dont use heet.Av8tor also stated in the post about opening up the detent lever that controls how much fuel enters the diaphram section to let more fuel past the needles.hope this helps a little.I bought some fuel called white lightning at the LHS that has 8% oil content but has 20% nitro.ran ok in my echo but the rings where not that good.maybe av8tor will step in and see what he thinks about the white lightning blend as hes done more testing.
