First of all thanks for your replies everyone
and I'm sorry that I have polluted this thread. Maybe I should start a new one.
Quikbird thanks for those two brands you named, I've heard about them seems to be a great web from what I've heard. Yep true I'm in France, nothing we can find here for the A833 sadly, even for mechanical shop for the motor it is really complicated to find one.
So I'll start look to passon and brewers for that
I went on jegs website and find the RST clutch thanks for that too. don't know yet if I will buy it but it is a good start
I will have to post on my thread I've been working on the bird and I guess some progress have been done so I have to bring you up to speed to let you know where I am now!
