I have searched and found that it is connected to a decompression unit and that my method for clearance wont work. can anyone tell me how to properly set the clearance on this valve? Thanks!
You need to turn the engine just past TDC (top-dead-center) so the decompresser releases that valve before you check it ;)
From memory you usally hear a "clack" as the decompresser lets go, you only need to go about 5 degrees past TDC...
With the valve loose as it is now, you should be able to turn the engine past TDC and see when the gap opens up to know when the decompresser has let go...
Good luck :)
