I did this on a MasterCraft snowblower with an 8HP Tecumseh. After messing with the nonadjustable carb that was on it, I said screw it. I put an Oregon adjustable on it, and the snowblower runs like a top. Your video was very in-depth and would be helpful to someone who is doing this.
So I have a similar Snow Blower. Leaks Gas through the intake side while running. Replaced the Carb with a new one and it did the same thing... Replaced it again thinking the one that was new was a return used. STILL leaked gas through the choke area of the carb while running... Set it aside... FINALLY found the problem.... I had sucked gas out of a tank using a Turkey Baster with a black ball. Must have gotten gas in the rubber area... Found tiny black rubber balls in my gas tank... I had reused the gas I had sucked out... No Fuel Filter... The tiny black balls got in the needle valve and let fuel flow.... I have a DR Brush that I went to start and checked the oil. Full of GAS... Needle sticking.... Glad I always check the oil... New Viewer.
I have tried two different nonadjustable carburetors from amazon, and they only work on full chock and then next day they would not work. This time I will try the adjustable carburetor and if that won't work. then I will try the Oregon brand adjustable carb. I saw one viewer comment went to the Oregon adjustable brand that work well for him, and I heard Oregon carb brand works well on the Tecumseh engines or OEM carburetors. Thank you for the video this help me out to decide which carb to work with.

Thanks in advance...your the only time that took the time to answer me on another question before...thank you
