A short story long---LOL---My zero turn started acting quirky-it would not run at full power and would begin to stall when put under a full load - like trying to mow some taller or thicker grass- never did stall since I would immediately kill the mower but obviously it was not right. I checked and changed the fuel filters-this one has 2 . One in the pick up line in the tank and one is inline just before the fuel pump unit. No help! So, before I dropped the big bucks to have the local farm dealer come and pick it up (at $75 per pickup and return) plus h=whatever shop charges that would result I thought "What the heck, lets give this stuff a try" I gambled $6 . I put in 5 ounces for the 5 gallons tank, and filled it with the gas I had on hand- should have been relatively fresh gas -no more than 2 weeks since pumped . Well, whatever the cause of the issue within about 15 to 30 minutes of low speed running- mostly at idle - the engine seemed to be idling smoothly as opposed to before where it surged but never died, I gave it a try at mowing. YEA!!!! full power and no bogging down - I finished mowing the yard and a part of the pasture (not yet grown up much so it is not requiring the rotary cutter YET) My only guess is perhaps a batch of either old gas or some water in the gas can or mower tank but whatever the cause it fixed it --and all for $6.
