So even if it would start I think you might have an issue with left over snow melting/freezing into a blob and jamming the snowblower.
I once used my snowblower and then left it outside for a day or two. Whatever snow was left in the machine froze and I had to bring it in the garage to melt.
These days when done I try and let the machine blow all the snow, then when the snow stops, I turn the machine off and drag into garage. The leftover snow melts.
I guess you could carefully go through the machine (off) with gloves on removing leftover snow but I never do.
