With those decompressors, I clean around where the valve seats & put a small piece of wire through the tiny hole in the top where the hose connects.
Check the black plug on top, is it a tight fit & sealing.
Use a piece of hose to test that the valve closes with suction.
Then see if it works in an engine.
Yes, I dislike the fact that you cant strip and clean this type.
With the valve out, youll soon find out if you have a good starter rope.
