I wouldn't say it is for anybody to do unless you have a longshaft motor lying around, the pressing of the blade carrier is not something you can do without a press I will drill the base to suit the motor tomorrow and see how it all lines up, it is not easy to drill the holes so you end up with the fuel tank sitting square on the base because nothing on the motor is square for you to take your lines off. I did mark out one of the dust covers from the underside of the motor with lines to square it off the height adjuster but it was a long time ago and I have no idea where it is now
