I'm pretty new to Morgan ownership but here is a random thought from my recent experience. If you are getting the hesitation particularly when pulling away it may possibly be a rear brake binding - I say this as 6 months ago I found I was needing more revs to pull away in my P4 (it has the Clubsport full exhaust and remap 18 months ago which has been an excellent improvement) and occasionally kangarooing or even stalling once or twice and the car also felt a bit sluggish at normal driving speeds. A bit embarrassing really, but it didn't occur to me it was a binding brake until I burnt my hand on the centre nut cleaning the rear wheel after a longish run! It was fixed quickly by the dealer just within warranty and has been fine ever since.

AlyMatt,
I have now removed the K&N filter out of the housing and removed all of the pipe work so the filter now sits in free air and the hesitation has now gone so looks like it was not getting enough air.
