Hi

I just bought a brand new axial .28 1s motor for my buggy. In the instructions it came with it says to use between 20 and 30% nitro fuel. I dont have any of that I only have 10%. I use this in my other cars and its fine but im not sure about break in. Will it damage my engine if I use it to break in? Also I bought some odonnell cold glow plugs for it because they were recommended for that engine but later I read that they were only for high nitro percentages. Will they still work with 10% nitro fuel?

Thanks
