Thanks again Anglo.
Yes I did find that site previously, a good source of info!
Just to correct what I said before, the Pioneer 620 is not exactly the same as the Danarm DDA110 but is very similar, the grips and covers are slightly different and according to that site the carb is too.
I'll post pictures up when I get a chance to take some.
Joe, yours is missing a small rectangular metal plate on the hand protecting bar, you can just about see the welds on yours where it was fitted.
