Thanks for all your suggestions, much appreciated! I've now broken in my new HPI MT2 G3.0 and am not leaning it out for the time being because of the sub zero temperatures, I think running it a little more rich would be better than leaning it out in this weather! I found taping up as many open holes as possible keeps out 95% of the snow. I blow it out with an air compressor and use a hair dryer once I'm all done playing outside. The only hassle is taping it up every single time I want to go out. Any suggestions about a possible quick fix for that?

Thanks!
