Hi all, I posted a little while back about my given to me free MTD Snowblower. I got rid of the old fuel, new spark plug and correct gap and a shot starter fluid for good measure. I picked up a bottle of carb cleaner from home depot that says to pour into the fuel tank and prime the carb and let it set. It was mechanic in a bottle Fuel system cleaner I thought it was worth a shot. Unfortunately no matter what it seems like it won't even catch or try to fire. A new carb was quoted at $98 from mtd directly. Any thoughts. It's a tecumseh engine. My Briggs and Stratton powered push mower starts year after year.
