Yes that's Simon's hand writing alright.
His signature black sprayed heads.
Did he do the muffler? He would pry the top deflector up a bit. It doesn't look like she was utilising all her power. Or she idled a lot in the cold winters of Montana?
Possibly the left side screen of the tri port is plugged then? Leach the F—ck out of the low always and give it 13,500 for that build.
Simon would send his saws out on the conservative side. Walker's send theirs out turn-key ready to go. No instructions needed. I bought a Walkerized 372 and a Simonized Saw about a month apart. People would ask me how do I like my new saw.
I would always say.." It's like a hair cut, I'll like it in a week" As my Poppa would always say: The difference between a good hair cut and a bad hair cut is 2 weeks..lol
After 11 year running ported 371/372,, Simon's saw amazed me when I turned it up after a week. That was 12 yrs ago and I remember the scenery of where I stood.
