added castor to fuel, not good
#1

My nitro only has 14% oil so I added Klotz to bring it up to 18% and now it runs like crap. hard to tune, wont idle, what a mistake. I read people claiming that there engine never ran better adding Klotz, wish that was me.

I was wrong, I had problems with the carb. Cleaned it up and 18% is running great.
