Re: (ET) Snowblower motor in E12?

[Dean Stuckmann <dstuck lakefield net>]

I think that heat may be a problem for the blower motor. I put one on a 
home made sickle mower and on an 80 deg day that thing was so hot you 
could fry eggs on it in as little as 20 minutes. And the sickle mower does 
not take much power to operate...
