RE: OS32 engine problem
Chris,
I suggest you go down to 5% nitro then.
There is nothing wrong with the fact that raw oil droplets are emitted from the exhaust of any glow engine, running on so much oil (15-22%)...
If you sniff those droplets, I don't think you will smell much methanol, or nitro; just oil and soot...
And since your engine has an ABN P+L set (no piston ring), you must use fuel that contains a good portion of castor oil in its lubricant package.
I hope you were not using CruelPower...
