Hi BB
I did pretty well run out of adjustment so split a plastic wall plug along 3/4, drilled a hole at the end of the cut & slipped that over the cable right next to the endcap. That's gives me about 4mm from the side plate & tension on the handlebar lever. I can feel drag on the rear rollers if I pull the mower backwards, if I wind the adjuster further out it locks up the rear from going backwards. Still have no fwd power at all.
