Those wheels are very magnesium. Just from how thin the casting is. They turn black and get chalky when in humid climate. Hartman used them well into the early seventies on the enduro karts because they were so light weight.

Most vintage racing kart engines have the fuel pump incorporated into the carburetor This is quite true for most diaphragm types. But in the early years Delorto carburetors were in use on a lot of the imports. They were adapted over to many of the American engines. Even used on those larger twin cy...

I have been working on building a cabin to finally move out of the city for a more peaceful life over the last several years. During this time not keeping up with what and who going on. One of the other karting forums seems to have been shut down. I have not seen any posts about it or who still has ...

Was this engine confirmed to be a Mac 15 saw? It has a tapered crankshaft with the early woven asbestos lined Max torque clutch. That has some serious value by itself. The block is stamped 52886A. That is the first model MC 49. It used the same block as a MC15 saw. The outer intake port was not dril...

Not so long ago I bought some fantastic repops made from stainless steel That is if you are needing stamped ones and not the
cast unimount. A place in Clackamas Oregon was selling them. The quality was first rate. They also made what I think is the Bug swing mounts.

Yes the Junior is an entry level package. Knobby tires, steel wheels, and no frame mounted gas tank. It is advertised at $219.50 with Clinton A-490.

Maybe a Super K Junior This one came out shortly after the final version of Super K and before the A-Bone. Does your kart still have the 1/2" steering shaft? I dont remember seeing the Junior having that large two gallon frame mounted tank behind seat. To post pics, scroll down and click Attachments...

After a closer look of your kart, I was totally wrong. I guess your kart is a much later model Bird than ones I am usually checking out. Way past the rear engine racing time period. From a glance it looked to me like a Blackhawk, until comparing them side by side. My bad.

That kart in your garage looks like a Blackhawk, not made by Bird Engineering. The kart ID in question, I dont think is a Bird. It does appear to be a racing kart. But uses the steering wheel commonly seen on Bird karts. One thing that sticks out is the side rails for seat. They appear to be origina...

I can see a rear caliper in two of those pics. Most likely a Palmini. Guess you will be getting more than expected is still equipped.
