Points that may help:
1. The kickstart, if operated to it's maximum deflection disengages and can not kick back. Take courage and kick all the way through the travel each time you go for a start.
2. Any amount of throttle canl make a small kick back into a leg breaker. You must learn to feel the engine fire and catch it with a tickle of the throtle
3. The choke on the AVL does not "choke" the carb of air. It richens the mixture by increasing the amount of fuel in the ratio. Remember to use it when it is cold.
4. The decompressor is not a decompressor as in the classic engine but a valve lifter. About as much use in starting as an ashtray would be on the handlebars.
A tried and tested method for cold kickstarting:
a. ignition off, clutch in, neutral selected, kick over twice.
b. release clutch and kick over twice (no fear of a kick back- ignition is off). Give a SMALL amount of throttle while kicking to suck some juice into the engine.
c. gently kick through to get to the compression stroke, then just ease past it.
d. Choke as required for ambient temperature.
e. Ignition on
f. One full Kick rtight through the travel of the kickstarter. When your foot hits the end of the travel you may need to blip the throttle to cach the engine.
If that doesn't work, repeat step c. followed by e.
Works for me.
