That plastic piece is still there and moves when moving throttle .Just for giggles, you may want to check the throttle cam. It's plastic and can break. My did. Caused me all kind of issues. There is also a throttle follower and roller. Mine is plastic. Has broken before. Both have adjustment screws also.
Good luck. Keep after it you'll get it.
Shouldn't need to touch that...set at factory, most likely something else
yep. i have gotten very good at replacing them with some clear fuel hose to measure (if i remember correctly) precisely 5/8'' outer diameter. some plastic epoxy and zip ties save you $35 for a new piece of plasticJust for giggles, you may want to check the throttle cam.
