Hello from Alberta and Engine ID HELP!

[deltabrent]

Hello from Alberta.

Just bought these engines online in a moment of foolishness.
Wondering if anyone can ID them? Hoping to build a Boardtrack style bike one day. With these if possible.

Any help with ID or where to get parts would be great!

Sorry, dunno. Any #'s on them?

Gonna look awesome on a bike!

..and welcome to the forum. Some amazing folks here and sure someone will have an idea or 2 for ya.

The cylinder/head shape is the nice part. I don't mean the chipped fin. You maybe can just have the bike with something obscuring the chip and still look natural. I would not think cooling is that adversely affected by that little ding.

Welcome!

Cool looking but I don't know what they are either.

Any ideas? I keep seeing similar stuff. Any idea what era they'd be based on the oiler etc? The flywheels are whizzer.

I think they're some sort of kart motor, but with no great confidence. Are there any marks or letters anywhere, were there carbs, and what make and type of ignition do they have?
