what is the air gap between the magneto and flywheel

robert pite, June 2019

loosen coil and put a piece of card between the magnet and the pick up,
approx 0.6 mm re tighten.
this will get you going.

Based on the spark coil picture here, the gap doesn't look adjustable. Please note: you'll need to copy and paste this next link BUT you'll also need to remove the spaces in the bit before ".co.uk". For some reason the owner of this site blocks some addresses and/or certain words.
