Hi everyone 
I have put just over 50 miles on this piston and I see discoloration already could this be from running premix and injected two cycle oil
any help  is appreciated here’s a pic of the piston  
thanks 

How about the plug?

Plug had some oil on it maybe I should go from a br9es to a br8es that is what was in it when my piston melted last time
Here is a pic of the plug 

want a shot of the electrode and insulator not the side of it and dont over light it

Looks good to me Bluntz, little rich but that’s good while breaking it in

Yea I would agree, I like the light brown of the combustion in the jug,I just wanted to see if the insulator matched it up.

  Here are a couple of pics of the plug 

Looking good to me. Maybe even a little bigger main jet if you you run wide open alot. Once its broke in you can switch to pure synthetic. I run 40to1 amsoil interceptor and its supposed to keep things clean. Last time I had my head off I had a little carbon on the piston but I have now switched to interceptor amsoil and I'll see if the oil cleaned the carbon off the piston. But dont do synthetic until fully broken in.  Good job, just watch them high rpm runs for problems like last time and double check that timing

Stop worrying & taking the head off to look. She's good. Nice & oily & won't come to any harm like that.
