CyberJack,
Thank You, you have been a great help.
I followed Deejay's clip and dismantled the machine as instructed.
I did not know what I was looking at but after cleaning and reassembling everything the lever returned to almost upright and the machine works fine.
I do not do a lot of work with it,(a small putting green)I expect it to last a while.
I would like to know the correct type of spark plug I should be using, I think the motor is original.
My next project will be to study the backlapping procedure, would we have a similar clip on that? I find it a bit difficult to follow instructions when I do not know the terminology of the items described.
Thanks again, very happy with the result, we have saved the machine.
Looking forward to your next advice,
Regards, Wally Pat.
