Speaking of colder plugs, my saw specs a NGK BPMR7A which is what I am running. I figured since I only have a muff mod and richened the carb, the stock is ok, but may want to go one step colder depending on how it goes. After pulling the plug for pics, I put a new one in, we will see how it looks after a few runs.
If I do go colder, what plug should I run? I forget how the heat ranges go......thanks
Those minor mods would certainly not make you want to run a colder plug. It will just foul up on you more readily, IMO.
NGK BPMR7A I run in all my saws and have run them in many 2 strokes for years. Some modified, some not. You are fine right where you're at !
