FOUND IT McCulloch 797 decompression valve

[Scott Kelsey]

As the title states I am searching for a decompression valve for a McCulloch 797. New or used is fine.

Are you missing it or is it leaking?

 

[Scott Kelsey]

The saw I picked up is missing it.

I know it is a 2 year old post but I just installed one in my 795L.

The Decomp valve was missing and replaced by a bolt screwed into the port. I could not start the saw in this configuration, too much for this 73 year old guy.

I finally found one (both the valve and the seat) on Ebay 3 weeks ago and installed it. I will give it a test start tomorrow.

Why in the world would someone remove the Decomp valve?

Same powerhead on my 895 Mac, it is a dream to start when using the Decomp valve.

The 795L:

Look close, you can barely see the threaded insert seat. I had to drill & tap the cylinder for the seat, then index the seat & drill a port to line up with the discharge port from cylinder to exhaust. Yea, it is dirty, I will clean up the carbon when I paint the saw this winter.
