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

My Snow blower only runs with the choke full on.  The engine is a Tecumseh HS50 Snow King (according to the sheet in my packet.)  Loosining the gas cap has no effect.  I expect that the next step is to clean the bowl.  Any advice on this task?

What this guy calls "the marty hole" is what gets clogged. You almost can't see it unless you've got good eyes (he's enhanced it for the picture).

So I was able to remove the carb.   And then I removed the bowl...There was some crud in the gas in the bowl so I took you-all's suggestion to heart and stripped the insulation off a length of 24 ga. wire and stuffed in every visable hole.  There was a pointed silver thing that I guessed was a jet control and shaking it and the float around, I was able to get it all back together.  Of course. after the fact, I realized it would have been easier to remove the float drop the silver thing in the hole and then replace the pin.  Half the illustrations I looked showed a spring on the pin but I didn't remember seeing one and the motor diagram that Sears shows doesn't show the spring, so it all got bolted up.  Turned the gas on, gave it a bit of choke and set the throttle about half way.  I held my breath pulled and on the second pull, the engine started.  Thank you to all who gave me the good advice.  After a short warm up, it was running full throttle with the auger turning and not a sign of a stall. 

I would not worry about the spring if you don't remember one.  I think that is mainly used on smaller 2 cycle carbs.

The silver pointed thing is the needle that opens and closes with the float to allow the gas to come into the carb.
It should have a small spring type thing clipping it to the float.

Glad everything is working now.

Good to hear you got it running well. 

You have achieve two important things.  1)  You understand your carb better and are able to repair it.  2) You probably saved $100.00 by not bringing it to a shop. 

So take that $100.00 you saved and treat yourself to something.
