Well to my surprise after running more fuel through it today the noise went completely away.......
I bought this engine used. Is it possible it had sat for so long that the bearings were rusted or gunked up causing engine noise and after I put some fuel through it that they got lubricated and quit making noise?
I just put a whole tank through it and it never once made a noise.....
