first make sure that the kickstarter is corectly installed, the kickstart shaft must be preloaded so that it pushes the kickstart towards the plastic cushion on the clutch cover when it is closed, and not have any gap.
then open the kickstarter, move it down by hand until you meet compression, then let it return and you will hear the clicking noise from the decompressor.
do not close the kickstarter!
from this point you must set the decompression wire's freeplay at 2mm.
then its all set!
when cold:
1.choke to position on
2.kick all the way very slowly 2-3 times
3.choke to position off
4.kick start slowly untill you find compression, let it return to hear the click and then a good kick all the way and it will come to live!
if not repeat from step 1.
when hot:
1.choke off
2.kick untill compression, release and give a strong kick all the way.
p.s. this procedure assumes that your carb is correctly set. (jet sizes,idling speed etc)
p.s.2. do not touch the gas at all through these procedures.
