 Awww. Look at what we found in the inventory room!

A "vintage" PK-80 build. Never run.

THIS ONE IS SPECIAL: FOR PRO/EXPERT ONLY.

The case features a specially machined front mount (for 1-1/2" tube).

DOES NOT HAVE REAR MOUNT. YOU MUST BE ABLE TO USE ADJUSTABLE REAR MOUNT, OR WELD IN YOUR OWN PEDASTAL.

Here's an opportunity to get one of the early plenum intakes for small carburetors, like the stock one.

This one comes with an SHA.

ANOTHER WORD OF WARNING:

The head is also a special head:

It's an old style 7.0cc compression release, which you have to be careful when using.

I have moved away from this design because the compression release valve poppet can hit the piston if you adjust it improperly.

YOU MUST NOT OPEN THE VALVE POPPET MORE THAN 1/8"!

THESE ARE RARE NOS COMPRESSION RELEASE VALVES. VERY LIMITED AVAILABILITY.

Folks that understand this will understand. Again, this engine is for experts only.

I will not replace the valve for you if you break it!

It is easy to protect yourself from accidentally opening the valve too far:

Simply install some kind of stop on the handle bar to limit how far the handle can be pulled.

And/or Do not tighten the cable adjustment. Make sure it's "loose".

I recommend taking the head off before running the motor and actuate the lever after the handle is attached to the handle bars.

Verify that the valve opens up just a little bit.
