cheers Ian!(the info is now free at www.ukpollards.com as an ebook )

here's a link to a pic of the mechanism for decompressing during startup of a Gx...

http://www.ukpollards.com/ebookgx160/page6and7d.htm

btw here's my method of checking compression on a Gx...

#make sure on/off switch is set to off
#remove rocker cover
# flip exhaust valve rocker off valve
# remove exh v/v rotator to save losing it
# screw comp tester into plug hole
# open throttle
# pull engine over with pull start about six times in quick succession (watch for needle climbing within gauge
# read off maximum pressure attained
# vent pressure from gauge
# repeat for other engine
If below 120 then strip engine and deglaze with a glaze buster from machine mart ( 3 legged tool fits in pistol drill and a few up and down strokes changes the bore from shiny to matt. If you do it correctly it will look like crosshatching on the bore)
# clean bore with petrol
# rebuild with new rings and refill with new oil
# redo comp test

done!
thanks again Ian.
Brian P.
