New 55 Rancher has limiters on carb jets

[GLOBOTREE]

The L and H jet adjustment screws have tangs-flanges, (limiters), on the sides of them that limit the total adjustment to one complete turn of the jet screw.
They are both set wide open (fully counter-clockwise) from the dealer.
My problem is that I cannot turn the H jet out anymore to adjust for
4-strokin.
What is the deal with the limiters?

You CAN remove them, with pliers I think, and adjust it properly, then just reinstall the limiters again. its quite simple to do. I did it for a friend today on a wildthing from poulan without much trouble.

dremel tool and some steady hands if they wont pop off (cut the tangs off if you cant remove them)...

You can clip off the "wings" that protrude from the caps and limit the screw rotation. On my 346XP, I cut the bulk of the wings off with diagonal cutters, then used a carpenter's knife to cut off the stub that was left behind. A dremel tool would be great, but I don't have one. Now it's just a plastic cover over the screw, and has full adjustment range. "EPA" stands for Extra Performance Available after you cut off the limiter wings.
