Hello, neighborhood friends. I'm looking for a recommendation for snowblower maintenance, preferably at my home. My engine is running quite rough, and my first guess is that I need my carburetor tuned, or that I messed up the gap on my spark plug when I changed it last summer. Either way, I'd rather pay someone who knows what they're doing take a look at it, and I'd rather not try to manhandle the beast into my hatchback to take it to a shop. Any ideas who to call? Thanks!
