The Bolens garden tractor sometimes get's the call to move snow. (I never use the 5 foot mower deck, I don't have that much lawn ;-) It's fitted with the opposed twin 23 hp K series Kohler
When the snow is light, I sometimes reach under the air filter canister and give the fuel delivery screw a 1/4 turn towards lean. That seems to up the "fuel efficiency". But it is easy to tell by the exhaust note when the proper fuel deliver is metered for heavy loads. There is a BARK there!.
Works the same way with the Fordson, When blowing heavy snow loads, the engine exhaust tone tells the story. It's amazing what another 100 rpm under load will do out from the pto. (NB Full power rpms is only 1000, idle is close to 100 . Those where the days eh! ;-)
No going too lean though! That can get expensive! ;-)
