10HP Tecumseh Motor: Help ID these parts

I bought this 10HP tecumseh to repower my 7/32 Ariens that is using oil.

I got the motor off CL and it starts and has good compression but I don't know what the odd electrical connection:



And this odd tube that appears to be a vacuum tube of some sort.

The electrical connector seems to be a charging wire for a head light option.
The vaccum tube I believe is for the prime pump, it should be attached to the carburetor.

Thanks that was the ticket. I got it started but it would surge and not stay running once it got warm. It would stay running if I used the primer bulb. I guess the carb needs rebuilt.

You're welcome.
Some people use seafoam cleaner as an attemp to clean the carb (I've never done it).
If it still does not run right I would agre with a carb rebuild needed.

Also, in your first picture it looks like that bolt by the hanging wire is loose.

Please direct all snow blower questions to the forums and not to me with PMs.

The Sears engine number, 143.94001 translates to Tecumseh engine model HMSK100-159244T, in case you have to look up replacement parts.

Toro 8/24 (38080) 1989
Toro 421-QZE (38585) 2008 (Gone)
Toro 721-QZR (38741) 2015 (Hemi Predator Power)

Experience is something you don't get until just after you need it.

Garage
On the primer line you can just cut off the end if it's still long enough and put it back on the carbs nipple. When it's too short to trim then you have to pull the recoil cover and run a new line from the back of the bulb. That or if you can find something the right size you can splice in a couple inches and you're good. It's always the carb end where gas eats up the end of that vacuum line and makes it swell and or deteriorate.

Make sure the windows are up before the snow plow goes by !!
