Hello. My 61 801 Powermaster runs badly under load. I've tried carburetor adjustments per the manual, but runs weakly under load. Was wondering...a few months back, a freeze plug fell out. The tractor got hot enough to run just a bit strangely. Shut it down as soon as it started to run differently. Put in a new freeze plug within a week and it fired up fine. Drove it a few minutes and parked it as I haven't needed it. Time to brush hog and it fires up and seems fine until put under load. Doesn't overheat, doesn't smoke, doesn't sound like the engine has rocks in it, just runs weak under load. Damage from overheating or carburetor our of adjustment? Haven't messed with carb until earlier today though. Sorry for drawn out post. Any advice would be appreciated.
Thank you all.
