What to do about Rocker Arm Adjs.

Turns out I was able to adjust the rockers. I guess because the adjustment nuts were so tight, I thought they were bottomed out.

Engine running quiet except for just a hint of tapping. I had set them at .10 & .20

Anyway, thanks for all of the suggestions.....

That's what they call an "Interferance fit" so they don't back out on you !!
