Thanks for your concern mate and I don't think your butting in or intruding, I've always been pretty open to people, I find it takes down the barriers that able bodied people build up about Disabilities.
I've been in this chair for nearly 30 years since i was 18,(Broke my neck in a diving accident) I think all the damage is done mate, And all the Paralysis is from my collar bone down so my arms are only affected slightly.
I like to learn new things like this, all my mates talk about engines this and engines that and I just look at them blankly, so learning this is a start to put me on even grounds with them,Plus I want to really get this mower going I'll be rapt if i can.
And my late wife would agree with you and my daughter, they always tell me "don't overdo it", but you know I've always been very independent which sometimes is a good thing,sometimes not
Cheers and thanks for your help.
I've been working trying to get the last screw on the cover of where the points etc are, it's always one screw or one bolt that wont undo. will keep you up to date on my progress.
