OT: Repairing Sears Snow Blower (Tecumseh)

L

LS 22 years ago

I have a Snowblower a friend gave me.

It's carb was gummed up and needed some cleaning. I took the carb off and cleaned out the bowl and checked the float and it works. The fuel lines are new and filter replaced. It has a new plug and the plug IS sparking.

When I push the primer it drips fuel on the ground. Is this the overflow of the bowl? when I try to start it, it will backfire and do nothing.

It has a lever that adjusts the choke. It looks like something should bolt where the flap of the choke is, like a air cleaner or something. If you go to the Sear website and look at the diagram of the motor, it does not show one.

What do I need to do to get this thing to start? Got 6 inches of snow coming this weekend. :)

I noticed the fuel cap says 40:1 gas & oil.

I used the gas I mixed for my weed whacker. I cannot remember the mixture. Could I have too much oil in it??

Had almost Identical probs with a Sthil brushcutter. the shop said it was fuel overload and leaned it right down, the vibration had caused the mix screw to wind out too far. The manual said get it checked after every 10 hours use, this happened after about 80 hours during the gorse season.

works great now.

I don't think it has a screw in it. If I'm staring at the back of the carb, looking at the choke flap, there is a opening on the left side. It's a hole with nothign in it. Does that mean the screw is GONE?

True single performance tuned exhaust, high-capacity heads and high-compression pistons? Sixty over with custom porting, stiff reeds and a K&N filter?

Why they never made oggers with clutches rather than sheer pins I'll never know... I have a dirt driveway and chew up at least 4 (usually 2 per snow storm, first 2 storms) a year AT LEAST!

if they're like tucumseh mower engines, it's cuz the dealer gets $50 a pop to change sheer pins and clutches would last too long... (took me 2 sheer pins before i found out that i could buy them at OSH in a 4 pack)

Mine has to actually run first before I can break sheer pins. :)

Keep the shear pins in. They are there to protect the auger gearbox. Brass gears inside the auger gearbox. A fist full of shears is way cheaper and easier to do than the gearbox. Drop the shoes down on dirt, ya ain't scraping down a dirt drive with a blower.
