Agreed yes you do. Does the motor turn by hand?

Hi guys, 

right, pinion is activated with method used above. Its not turning the whole motor though. In gear I am unable to move the prop by hand, is this normal I don't know how much force is needed to turn the motor and engaged gearbox. Should  access the flywheel and try to turn that?

Getting a bit over this problem now.

Just tried again and can turn the prop, tried key and it tried to turn over. Now back to nothing, other than a click. 

Smudge or KAndrew are either of you available, beer/spirits to either of you who can come around and diagnose please?

The starter pinion teeth were worn out and trying to climb out of the flywheel teeth giving the impression the starter motor wasn't operating.

You too Smudge!! I was convinced it was electrical, actually never considered it was a mechanical problem. Anyway, got to meet Smudge as a result, and shared a few yarns. Just waiting for a price to fit the new pinion. Smile

The one thing I have learnt in my 45 years as a fix it guy is to never make assumptions. But I still do. all the time! Big smile

So are you saying that the starter was jamming, what’s the flywheel like.

Not very common with a elpo motor, was the starter lose.

Yes it was jamming. The flywheel was worn of course  but a whole lot less than the pinion. It has years of life left.
