Oily spark why???

[dmpatanis]

In my paramotor engine Sky 100 i set up my carb 1 and 3/4 the long screw(that the manual says),but when i unscrew for the first time the spark after 8flights an 1:30 trip and with paramotor the spark plug is dark and oily why??

I use Castrol TTS with 23ml for one litre of fuel(2.3%).

Thanks a lot.

it is more than likely that the last minute that the engine ran was on tickover, which will give an oily plug, on any 2 stroke

to get a true idea of plug colour. rev on full for one minute. keep the accelerator on full whilst. hitting the kill, then remove plug.

it won't be oily.
