Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

Hi everyone this is my first post! Well let me first say that I am a new homeowner and I acclaimed a new to me snowblower around November last year. I had used it all winter and it wasn't running that great. It took many pulls get started and once started it would die. Then I would have to turn the choke up very, very, very slow, so by the time it was ready to blow I was 10, 15 minutes in... Anyway how do I go about disassembling this and cleaning it? Any videos on my model?
