Compression

[thumper68]

What is the compression suppose to be for a 2 stroke 80cc engine? Is there any special way you need to set up for the compression test? Any info would be helpful. Thanks. thumper68.

I do compression with motor cold and throttle wide open - I like to see about 125#, but some motors on ebay may be lower.
