Took my Max II out yesterday in snow deeper than I've ever driven it in and for the most part it took everything the 16hp B&S had to move through it at a decent pace. I was full throttle for the majority of the outing and got stuck in a few ditches as well which I'm sure strained the trans and engine quite a bit. By the time I was done probably 20 minutes total there was signs of trans fluid around the vent plug and the engine was surging at idle. The engine wasn't surging before the ride but definitely was after so my question is this. Does the newly developed engine surge at idle have anything to do with the extended full throttle driving I was doing yesterday? That's all I've done lately is repair the damn thing and now this so I'm just trying to get an idea of what might've happened and how big of a problem do I have on my hands. Any feedback would be much appreciated. Thanks Cup
