I run a service truck but I don't repair forklifts or really work on engines at all. I do welding repairs mainly.

I just bought a Nissan 50 forklift:

Model: KAPH02A25PV
Chassis #: KAPH02P090687 the "09" part is almost impossible to read, but that is the best I can come up with.

The guy I got it from said the mixer/carburetor os scored, it's a CA 55, I have a new one ordered and waiting for it to arrive.

It will start and run, just runs rich. To start it you have to turn the valve on the propane tank for about 1 second then turn it back off. Then start it, then barely turn the bottle back on slightly. If you do it right it will run. If you turn it on too much it just dies.

I am trying to figure out the vacuum lines while waiting on the mixer to come in. Can someone help me figure out the correct sequence to the vacuum lines, I don't think they are hooked up correctly and I don't know where the port on the intake above the carburetor is supposed to go either.

Here are some pictures I took, any help would be great, I can't find a diagram anywhere.
