Is it possible to do a compression test on the 450 motor with the auto decompressor ?

if so what readings would you expect.

cheers

No, you can't - as you stated the AD mechanism nixes that. What you are after is a leak-down test:thumbsup:

To perform the leak test (provided you have the equipment)
You will need to remove the valve cover and manipulate the Auto Decomp weight in order to release the exhaust valve for testing.
