There's some real haters of gas 4020's on this site, but my "Ingrid" has been a pretty reliable snowblowing tractor.
Some days ago @-12?F there was a little icing at the top of the carb before she was fully warmed up, not affecting smooth running, after I blew snow for awhile and worked her the manifold was hot enough to melt that off. Didn't get an "after" photo though.
