Okay, I've been doing research for a couple of days as time permits and I just can't find the anwer, so I thought I'd ask those in the know.

I'm building a wheelchair conveyance three wheeler and have all of the engine parts together but don't know where all of the lines on the carb go.

The engine's a 150CC Chinese clone GY6. I know where the fuel in port is and the wiring for the "choke" but don't know what to do with the other lines, some of which appear to be vacuum lines.

Any help would be greatly appreciated.

 

See if you can find a service manual (good luck!) or find one installed in a machine and trace out the lines.....

 

Yeah, the service manual idea hasn't panned out.

I've also considered looking at an installed carb. Perhaps that will be my next step.
