Hi walt207. A very warm welcome to you; nice to see another local on TM. Regrettably, I have no experience on the M3W but there is a wealth of knowledge on this forum so I am sure you will have some useful feed back soon so set your computer to stun.
If this is the only problem with your new Ozzie 3W you have done extremely well given the unique nature of the vehicle.
This sounds like a relative minor issue but you should run it by Morgan Cars Australia in the first instance. Good luck with a fix if it’s necessary and I would welcome a catch up when you’re out and about in Sydney town.
