A few times in the past I’ve poked fun at you guys for how fussy you are with setting your timing and adjustments. For over 30 years, I’ve just used my butt dyno (thank you for that term, I love it) Never thought it would be a big deal as long as the engine ran good. Use the 10-20-30 method, air gap at 0.10, points at 0.20, plug at 0.30 then spend the time on adjusting the carb. Always got the biggest bang for the buck out of air to fuel mixture. WOT just set the governor by ear.
Well over the past few months I’m rethinking that. Most likely as when I use the rototiller I’m thinking if I could get 5% or even 10 % better performance with spending a few bucks and a little time it would be well worth it. May be even save a little wear and tear on the cub. Being conservative I would guess I run a lower RPM 3000 +. Never thought I needed the extra and thought I do not want to push the old girls. This winter and next spring I hope to have more cub time than this past year. So in short you have converted me. I’m going to spend a few bucks on a new tach and timing light The ones I have are from the 80”s and they were never much good any way. I might just find out I was where I needed to be.
