Thanks for the replies.
I had the role of the kill switch backwards. Thankfully I'd seen your post about removal because the internal rubber cover was damaged (prior to me) and wouldnt reinsert so Ive plugged it briefly with a bolt.
Popped it all back together. First pull and the thing screams back to life in what I assume is the first time in many years and idling comfortably. I wasnt near any work
In respect to carb modification and RPM control.
I have an RPM and hour metre that wraps on the ignition wire. Whats an optimal figure? Ive never actually bothered to check any of my older 2 strokes. Theyre all just ..Loud.
What is the benefit of the modification? Removal of the diaphram and poppet and manual control of the rev limit?
What is the purpose of the trimming of the fins/ridges on the Cam? Is the steady ramp just to allow for more moderate applied control of the throttle on?
