Re: What mod should I get.
Oh, I'm eating it all up. All seems like good info. I do have a welder but not much time in on it yet. I used 16:1 for the first 2 gal using Lucas 2 stroke oil. Now I'm down to 20:1
I'll definitely implement the spark plug and oil upgrade this weekend. Let that settle down a week or two and try out re jetting. Still though I wonder what happens to the sound level when going from stock muffler to an expansion chamber with the attached mini muffler.
