25hp Kohler
45 blower
relief set to hold 14hg
2200 wt generator
No load and no heater on (which puts a load on the generator), I'll drop a couple hundred RPM under full load.
Note; I'm not positive of that though, cause I throttle up to 3200-3250 with the vac hose hooked to the vac port, but wand not on the carpet yet.
Under 14hg load and when the heater kicks in, it'll drop 100 rpm or so
