Tread lightly, as you seem to be doing, but be aware the "edge" is ahead in the fog you are travelling through. |
I dont count for the NM lubricant so I am running rich on oil - but then, since I am running a hotter fuel its probably better to run with more lubrication.
I have since doubled the ratio of NM - and the simple answer is DONT. The engine is showing signs of running lean which for a 1 - 2mph inprovement is not worth it. However for those with a tanaka engine a 50mls/gallon mix of nitro fuel is worth it just for the improved starting.
If I had an adjustable carb it might be worth playing around with it, but as I dont and dont have the money for it - I will leave it at current levels
