Went and ran a couple of tanks through the latest Super XL-130. Rings need to seat still. I am thinking the throttle shutter/bore may be worn a tad as there is some obvious lateral play. I swapped from the external idle screw to an internal, so the different contact point on the stop may be contributing to it. Every once in awhile it seemed to hang up a bit when released. A quick blip and it returned fine.
Managed to cover my boots with chips properly, though.

Clip is a tad long. Some funny sounding guy from BC went on rambling for a minute or so at the beginning.
I have 3 76 and really like that model. The latest 130VI I can hardly pull over. P&C pristine. I must do a compression test on that saw.
