A Two Stroke Tecumseh

My Brother-In-Law dropped off his parents' snowblower, as they had recently purchased it, but it was not running properly at all.  
Not sure what the issue was, and no way to recreate the problem as the pull recoil rope had

nearly broken, and there was no way I'd be able to use it to start the engine.
Only thing to do was to crack into the case, and start monkeying around inside and see what I can learn.
A few bits of hardware were missing, but nothing major, considering it was all just outer casing bolts. Sure, they're pretty useful to have it all, but I'd be more concerned if the hardware on the engine was missing.

The first big reveal when I took off the top plastic case was the big "TECUMSEH" logo on the Pull Recoil. Imagine my surprise, and delight, when I saw that.
Even tho they may have a reputation for being junky engines, they really aren't that bad. They're fairly well constructed, they are... kinda eccentric? Or... something along those lines... But overall they are decent engines. 
The carburetor was really easy to access too, with its own little door.
A pair of 3/8" bolts is all that holds it on, and you have easy access to the bowl nut, so you can drop the bowl.

However, as it was pointed out, I think I may have not read the label as literal as I should have.
Misinterpreting the label as "ON/CHOKE/OFF" instead of "CHOKE ON/OFF"
My bad, but I still kept the operation correct, any way you look at it.

I mean, could I have reversed it back? yeah, but I didn't really think about it, until "AFTER" it was picked up, and I had explained it to him.

After cleaning up the carb, and the struggle to reinstall it, the snowblower came back to life, I also replaced the pull rope. Not that it was really bad, but I figure it was the right thing to do with the service.

When reassembled, I even gave it a little bit of a test with some leftover.. uh.. snow


IF you want to call it that, but the snowblower did a good job blowing it, even tho it's not really intended to be moving heavy snow like this.



And because the on/off switch fell apart, I changed it to a normal on/off switch, instead of a key switch.
I mean, the key is kind of pointless, but I understand it's for safety to prevent kids from playing with it, and getting hurt.

I would say this was a successful repair!

Anyway guys, until next time.

Stay tuned....
