[wanaraceme]

sup thanx for reading, i had to take my engine apart for a few reasons and i got it started but there is a knocking noise coming from the front right of the head. im thinkin its either the valves arent set right or my timings off or can it be the decompressor. hell maybe i just suck at fixin stuff but please ne output would be helpfull. thanks alot

well mine started knocking and i found that the timing chain tensioner was all the way out because the chain had stretched. it sounded much like what you ahve described. might want to check timing marks and if you cant seem to get them right on the money then it is most likely the problem.
