Had a problem with the carb on mine because someone that looks like me left gas in it. The float bowl had a lot of gunk in it. Main jet was about 60% clogged. Was easy to take the jets out without removing the carb. 30 minutes to take the 2 jets out and clean. Now I don't have to run it with the choke on. I bought extra shear pins because I read reviews that these things break shear pins. Plowed through 14 inches of paste the first year and have yet to break a shear pin. Was throwing heavy wet snow a good 30 feet.
