I thought you had removed the limiters?

The saw runs with the L fully screwed shut, CCW, that aint right, is it?
Cory I think you must mean clockwise not counter clockwise [or anti clockwise]. The screws can be shut only clockwise in turning the screwdriver.
The 372 with the adjustment limiters on the L or H speed screws can't be closed off tightly, the restrictors prevent that. So it will run when you think you closed them tight.
I disabled my needle restrictors by cutting the white plastic tabs off with a Xacto knife, very easy to do, just pull off the airfilter and cut away.

His new 372's have different limiters then the old 372's we are used to.  There is a pic of new 372 carb IPL I posted in this thread.

They really don't have limiters at all; they take the special adjustment tool.

  Thanks guys, I guess my 2006  372 doesn't qualify.  :D
But just to get this straight even with these new style H & L screws they still can't be shut off tight ,right?

The carb limiters on the new 372XT's has a spring loaded limiter ring around the H&L screws.

You can just push the limiter ring in with a scribe or little screw driver and then turn the needle valve all you want to with a regular screw driver. You can turn the needle past the stop and have a new range of adjustment.

You don't need the combination tool necessarily.

But the two tool deal is hard to accomplish as the chainsaw comes from the factory. It is very easy to do with the needle boot and top cover off the saw or with the carb removed.

It would be almost impossible to adjust the needles with the chainsaw running with two screw drivers whereas with the special tool it can be done with the saw running without removing anything from the chainsaw.

The limiters can be completely removed if you screw the needles out or you can cut the tabs from them and re-install

I'll see if I can do some adjustment with the info you provided here, Mr 660magnum, thanks.

Holmen, it is indeed ccw/counterclockwise, they are maxed out turning ccw and the saw still idles and runs. I'd like to make it richer.

It is much easier to fiddle with the needles with the magic socket screw driver but the frugal person can do it with existing tools about the shop.

I just took the tabs off the ends of the rings on my needle valves
