Bit sparse on the text but the pics make up for that though (Ihope).
A Throttle Lock, I got the idea from John C. MIG#626
I cut it out of 3mm thick PVC, filed and sandpapered the edges of the "C"
so that it fits between the throttle and the switch-housing.
Fitted it with a small angle-bracket thatīs attached to the bottom of
the switch-housing by the screw that holds the throttle cable retaining bracket.
The thumb knob is a bit of plastic junk I found in my junk-box.
It works Great
Good Luck !!!
