Thanks fellas. Once I installed the drive assembly back into the mower and connected the pedal and actually used the pedal it seemed to have "moved" everything back into position and it all seems to be working as it should. I guess loading up the clutches by hand and then using the mechanical advantage of the pedals is two different things.
It does seem to be working as before now. I adjusted up the nut holding the entire drive wheel and clutch pack once I had a play with the foot pedal. Luckily it is something which can be done once it is fully installed into the mower as previously mentioned by Murray.
Whilst I was in the Greenfield agents shop picking up the new drive belt tensioner pulley he said a bit of low to med strength Loctite wouldn't go astray. I also picked up half a dozen shims incase I want to adjust the pedal to suit.
After assembling the drive shaft and new chain I typically thought I would check the other pulleys now that they were difficult to get to. Turns out they all had rough spots so I took everything apart again and though I'll just replace all the pulleys. Hopefully the new motor turns up tomorrow to keep me well and truly busy for the rest of the week after work. At least the belts are in good nick as is the main blade carrier spindle!!
