I would lean towards the carb, fuel pump or filter. If a cam lobe was wiped I would have expected you to complain about backfires or running on after the engine was turned off. The only other thing that bothers me is this comment

"could it be unadjusted valvetrain? i tried to do the hose in ear adjustment but it seemed that there was a slight ticking on all the rockers no matter how much i tightend them"

If you suspect the valvetrain adjustment I would seek a good valve adjustment procedure to eliminate that variable. I have never used a hose in my ear to set valves. There is always ticking, but there is a distinct difference between clacking and ticking.
