There's a limiter on the "H" screw that must be disabled.

Typically there is a little plastic tab the prevents movement beyond a certain amount.

There are many schemes on the needles to keep them from moving.

Look at it and see what's keeping it from moving.

It looks like there is some plastic tabs, part of the adjustment screw. The thing is, they are beyond where I can reach them in an obvious way.

I came across this problem the other day. I was able to slide the plastic screw cover with the tab completely off the screw.

By "slide", do you mean pull the plastic part out? How do I get a grip on it?

Also, is here any benefit in drilling out the intake cover? I have seen pix of where someone made some neat holes on the back of the cover for fresh air.

Correct.

I was able to get behind it and push it off

It looks like these orange plastic screws are in side part of the carb casting. They only turn a quarter turn to the right and stop, and they are currently as far open as they can go.(That's how I found them.)

Also, is here any benefit in drilling out the intake cover? I have seen pix of where someone made some neat holes on the back of the cover for fresh air.

X2

Drilling holes in some covers can mess up the air filtration.

These are not high performance saws that need additional air to breathe. Keep your air filter clean.

Cool, Thanks for that.

I think I am gonna take the saw to a small engine guy to do the carb. I cant see how to get these screws moving...
