I have been a small motor mechanic for about thirty yrs or so, worked on tons of two strokes and four, whatever make, from briggs and scrap iron to Honda, quads, skidoos, motorcycles,chainsaws, etc, after that many years doing it, don’t do it for a livin anymore, just putter to keep up my skills, have an older Yamaha 350, and Suzuki 300, go out to the sticks and take them for an occasional rip. Live in Northern Alberta, most of my life, traveled across The States more than once, been across this big country also. Nice to have sites like this to get interesting info from, and a person should always be in a learning mode, that’s the secret to longevity. Take Care.
