12 HP Honda single - BCS walkbehind, single-stage snowblower attachment. Crude as it is, this thing has always been something of a beast.... chewing it's way through all kinds of stuff. Had it out for a couple hours today in 18-24" of the white and fluffy... and it seems to me like it's only putting out maybe 1/2 or 2/3 of it's usual power. Along with that, something has frozen in the throttle linkage so it only goes full-bore.... got it in the garage thawing out right now. Assuming the throttle linkage is a separate/unrelated issue, can anybody suggest what I am looking for to explain the power loss ? No smoke, so I am guessing I haven't broken a ring...

That throttle issue may be the cause . It may over-rev at no load and still not get full throttle when under load .

Snow Blower Seems To Have Lost Power ?

You have to go back 35+ yrs to find points and condensers on small engines! Sheared keys are mainly a mower problem.

Too lean of a fuel/air mixture also causes backfires, so the fuel system is the best place to start.
