Using different nitro content.

[s14]

I went at the local LHS and bought some 20% nitro thinking that that was what nitro % i usually use on my savage.

When i got home i realised i have been running 25% nitro the whole engines life.

Now i have already opened the bottle ( i had a whiff cause i love the smell lol) and i cant return it.

Will my engine run on 20% then be able to go back to 25% nitro? Or should i ditch the 20%?

I'm not the best tuner of engines btw

Tuning is easy if you have a engine with decet compression, and NO air leaks. Set your needles back to factory settings, then start leaning in 1/16 incerments. start w/ high end needle then move to low end .. You will be fine ..

Thanks heaps. I wasnt too keen to ditch the 20%
