12 volt Question
I have a walk behind snow blower that has a 120 volt electric start and a 12 volt headlight. My questions is where does the headlight get the 12 volts from? Does is come from the 120v starter or is there a separate source somewhere within the engine shroud?

Yep, just plug an extention cord into the wall and the other end into the starter switch.

The engine's magneto has a separate lighting coil that generates electricity for the light, or it has a separate stator to generate electricity for the light. The bulb is also most likely a 6v bulb, rather a 12v.

It must be kind of like those lights on a bicycle that are powered by a thingamabob driven by the wheel, but I don't know how many volts that is.
BTW, does anybody know where the light goes when you turn the switch off?

Most of the 17 HP+ 2/4 cyl. engines come with or can be equipped with an alternator just like a car. Even had one on my Bermuda/Greens grass mower.

Yeah, you have a little stator either external to the flywheel or under the flywheel (since it is probably a Tecumseh Sno-King engine).

Speaking of Sno-King engines, since Tecumseh has gone out of business, where can I get a carb (preferably new) that has the adjustable idle/running jets???
I bought a 'new style' (non-adjustable) a while back, and it's a POS. (Sorry.)
ETA: The Briggs & Stratton engine on my new (figuratively speaking) snowblower has a 'lead' that is 12v. Nice to have 12v available!

Give me the numbers (just the "spec" number will do) off your engine and I should be able to find you an adjustable carb part number. Then you can price it out.

Thanks, Kal!
There is (correction, WAS) a small engine repair shop near me, but, they closed up shop.
I took the manual w/part #s with me, and they handed me that 'non-adjustable' carb, saying that it was the replacement.
One guy said that the 'old style' carbs weren't available, any longer. (????)
That's basically why I asked.
I'll look up the info tonight, IF I can remember it!
Thanks.

More likely the bulb burned out. Check across the lamp leads with the engine running and your voltmeter set to AC.
