There's a thread downstairs in the 700/900 section of the forum....how to replace the CPS.

1. Is that methodology fully easily applied and transferable to be re the 240?
2. Will a 10mm ratchet spanner do the job on a 240?
3. There's also a comment downstairs about lie on top of the engine and use one's left hand to wield the ratchet spanner. Is that the or a good
modus of approach to get at that fixing screw/bolt on a 240?
I'm asking now in case of need. Time spent on reconnaissance is never wasted.
