Hi guys. I have an old MTD 21 inch snowblower with a 2 stroke Tecumseh engine model HSK 600. I was putting some fresh gas in it and gas started dripping from the carburetor.
I thought maybe the float was stuck down and was running out of the air intake at first. But when I tipped it up to get a good look at it the gas was dripping from tiny little tube just about
an inch away from the gas inlet tube from the gas tank, toward the front of the snow blower. It is a smaller diameter tube than the primer tube. It looks to me that there should be rubber tube going somewhere but I can't see where it would go. It could maybe be a vent tube but I'm not too familiar with Tecumseh 2 stroke carbs. Does anyone know what that tiny little inlet or vent tube is for and what would cause gas to leak from it. I took the bowl off and blew out all the holes inside the carb that I could get. The float works freely. I put it back together and put a little gas in the tan and let it set a little bit and it didn't leak.
But when I pushed the primer bulb a couple times it started to leak again and it won't start. It has good spark a little over 90 lbs. of compression.
Any suggestions anyone?
Thanks.
Jerry
