Bought a new model 2410 2-stag snowblower 11/15/2019. Did not use until this winter. Upon purchase I followed startup instructions, which included filling with the prescribed oil which was supplied. The snowblower initially started but it was spewing heavy white smoke and oil through exhaust. After many attempts to resolve, including new spark plug, I finally had to take to have serviced. Bottom line, the oil was overfilled causing it to clog the carb. They had to remove and clean the carb, remove oil and replace with new oil. Nothing major, but nonetheless $100. After investigating the internet, I found several similar cases. I think their start up should be modified to let customers know that the oil level must be checked before any added.
