I'm back! Loaded with questions. Searching for a little more out of a 129. Not wanting to go to the tractor pulls. Plowing tilling etc. Workhorse improvements. I read on a website about changing some springs on/at some valves. Pretty incomplete info. Nothing about the springs, other than need to be twice the power? Strength? Applied power? Stronger? Not sure the correct terminology for that. Where to buy? Minimal info. So anyone have ideas or proven improvements? Thanks for any and all help is appreciated.
