OK, serviced the ol' H for the winter; I use it to plow out my lane when the snow makes it necessary. Anyway, service included oil and filter change, tune up kit and plugs, drain radiator and refill. This year I replaced the radiator hoses, too. Anyway, tractor was running great. Ran it up the lane, pushing only 5" of snow. Turned around and the thing started running REALLY bad -- miss-firing, lack of power. Ran it back to the barn and parked it. Now I notice a "vent plug" shown in the Operator's Manual, located on the side of the thermostat housing. Was I to bleed off air as I refilled the radiator? Did I foul up here, and damage something? If not, why did it suddenly start running like a d@mn Yugo? Thanks guys.
