I think i might have a small leak. The bottom of the HSN where the nipple for the fuel line is. When i first got the motor i loosened the HSN to move the nipple so the fuel line would fit comfortably and now i guess it un-sealed it. It only has a really small leak and i dont know if thats enough to create the kinda heat im getting but yeah, Im gonna try to seal it all tonight and see what happens.
