Thanks bigted.
This is on a Rover Easytrim Xtra i4500.
I think you'll agree that a picture is worth a thousand words.
With the nylon washer under the screw head the mechanism tends to bind up.
As per photo it works & the old scratch marks roughly line up.
I think I will put some "Loctite nutlock" on the thread during reassembly.
Do you think it is better to use a silicon spray ,a grease or WD40 on the spring & centre assy to keep it free in dusty conditions?
The throttle cable bracket at the engine is an enigma. I only mention this to prevent other owners from slashing their wrists in frustration.
Twice I have set up the cable travel & each time the bracket has bent over 9 months.
Perhaps there is a man-cave secret somewhere.
I'll pursue that later but now I'm prating (look it up)
Many thanks
