Called PowerArc. Was told: After 1/4 second! The ignition reverts to TDC firing. Thus it is wrong (and, dangerous in my opinion with a banged tibia that still feels the "touch" of a kick back start lever) to kick it hard to start it. You give it a prod to get it close to start feeling the compression, and then "gently kick it over". No high rotation rate to get spark. That first spark is set at TDC -- ALWAYS (1/4 second to a reset to TDC). In fact, there in lies the danger. If you give it the traditional hard kick and that kick does not result in a start, but goes round to the next compression stroke TOO SLOWLY (there wasn't a very good charge of fuel and air the first time over, OR it didn't fire the first time over, but just pulled a good charge into the cylinder, it will fire with standard advance!! And THIS time it Can kick back! The advice was as soon as you give it a nice little kick, GET YOUR FOOT OFF THE KICK STARTER! So I have a good piece of advice for Power Arc. All the problems (and the danger!) could be fixed if it could be programmed to stay at TDC firing for TWO ROTATIONS instead of one. If TDC firing was enough to get it through and over compression from the first firing through the second, now with regular advance, it will work for the second rotation as well. So even if you kick it so hard it goes round a second time with a weak or even no firing the first, the second won't backfire and kick your foot off. You could even program the ignition curve to stay at TDC (NO possibility of kickback) until you flipped the switch to the second, normal curve. But that's not the reality today. So GET YOUR FOOT OFF THE KICK START QUICK! As to my problem getting stuck in the middle of nowhere? Carry a jumper wire for diagnosis and possible cure as described above.
Strewth, what a carry on. I’d bin that and put something ‘sensible’ on it!
There’s plenty to choose from.
