So I got this wheeler new in 2003 an it has been risen HARD, wrecked a lot and not well maintained while I was teenager. It has been sitting in a barn for 5 years and I finally have a shop to store it and use it at my home. So I replaced the battery and it started right up but ran rough so I decided to tune it up clean carb etc.

It was spitting gas out of the intake so I decided it was a good idea to adjust the valves. I’ve aligned the timing mark 20 million times and I still have no play in the rocker arms. I don’t think its on the compression stroke though. So my question is should I go ahead and try to adjust it? Also I’m not entirely clear on where I am supposed to place the feeler? Does it go directly below the nut?

Thanks for any help you can give!
