My ole P!! dragster was set to loopy 600 when I got it and Trixie Combat retrived before Katina struck started up - settled down to impressive to me 450 easy as ya please but my JD Poppin Johnny twin tractor cleat buster settles down to 240-ish but that's like mid range rpm for a one lung Lister type and WOT on ole hit and missers flywheel pleasers. I like Cdo @ 900 for road use as 1000 is a bit bussy to me but when I arrive at bike gathering, which takes effort not to out here, I set tumb screw slides down to 600 ish and folks tend to cluster to gather the puff balls. Its definitely a harmful practice as so many other things in life bad for us, for a time. I love hearing my Popping Johnny in back ground pulling a trailer to collect storm debrie with me walking all over here and there dragging limbs back while its idling in great great grand ma 1st about .3 mph but in no danger of stalling. I just climb back on and giver the gas 1800 rpm 3rd top gear hauling ass away maybe 4.5 mph. Plowing or bladding when it hits a big root or rock knob it simple stalls right down silent but for a slight inhaling noise then the governor kicks carb throttle WOT KAPOW KAPOW KAPOW POW POW POW POW>>> digs in and carries on through the root and a few bounce back rehits and the rock shears off too then PUtt PUtt PUtt then the next tough spot.
Gotten from 89 yr old who'd modified with two red vertical posts replacing brake peddles so when the plow dug into virgin deep sod and the front tires lift off surface could steer like a dozer...
