Next tank it was so rich I wouldn't even really run halfway through the tank. It took alot of leaning to get it back to where I was the tank before. It seems to be on it's way. I am curious as to what plugs work on nova besides novas. Rick recommended a hot plug on his engine, but that is all he told me. I am getting some last minute parts ordered for the first oregon pro series in medford and was needing some plugs. What do you recommend?
