OKej, not a low power issue... Put back the battery, pushed the button, it grinded. Pushed the button again, it engaged perfectly and fired up immediately. Turned it off, pushed the button, it grinded. Pushed the button again, it engaged perfectly and fired up...
So, I will tighten the wishbone clip and see if the engagement statistics improves...
If it doesn't help, what can it be then? The gear seems be running smooth on the sleeve. It seemed to engage perfectly before stretching out the return spring some. Or just good luck... Now it engages almost every second time... Would a new clip really do it... And maybe a new return spring... And maybe a new gear... A whole kit...
Seems like a very delicate function...
Will also measure the teeths. But since it engaged perfectly almost everytime, can the gear really be weared out then?
Well, I'm getting there... soon, I hope...
