What the heck are these??? SK jets???

[JMortensen]

I bought a whole bunch of jets from ZR8ED, and about 1/2, maybe a little more are Mikuni jets. There are quite a few which I just cannot identify.

 

I've only worked on the later style Mikunis, so I don't know if these could be from an earlier style (I **thought** all the jets were the same) or if they are from SK carbs or what. ZR8ED was into Webers so I'm sure he would have known if they were from DCOE Webers...

 

The jet blocks have 2 different numbers on them. One bag says 7772.4 and another one says 7772.2. I'm used to OA, or 8.

 

Anyway, I got some of the holes in my tuning tackle box filled, but not as many as I'd hoped. I'm looking to possibly offload these once I figure out what they are.

 

EDIT--I should say that there are probably 80 miscellaneous jets of these types. I'm not just fixing to sell the 11 that I've taken pictures of... there are quite a few more.

I found this on Zcar.com on Sk racing Carbs

Here is a breakdown of the parts:

 

The following are interchangeable with the Weber DCOE carburetors:

Main jets

Air correctors

Idle jets

Emulsion tubes

Pump exhaust valves

Pump rod, spring and piston

Auxiliary venturis (45 DCOE only)

 

The following are interchangeable with Mikuni PHH late model carburetors:

Pump jets (Mikuni calls these pump nozzles)

Floats

Needle Valves

Fuel Union Banjos (I think Mikuni calls these Fuel Pipe Assemblies)

Thank you SHO-Z! Good info there. I ended up trading them to a guy who thought they were motorcycle or jet ski carbs.

 

This whole deal worked out really good for me between the ones I kept, the ones I traded, and the ones I'm getting back in trade. Thanks again ZR8ED!
