A follow up question to all you kind folks (thank you for warmly accepting "newbie" questions): is there a good definitive "shop manual" that is available for purchase, since it sounds like a lot of you are forced into, if not enjoy, doing the work yourself? There are some very good mechanics here in Texas, both for motorcycles and for vintage cars, but I am not aware of anybody with Morgan experience, let alone 3 wheeler experience. If I had some help from somebody more experienced, and access to a decent shop, I could learn my way. It looks like I'd need an EZcarlift to deal with the back wheel and possibly belt tensioning. Dealing with the "coupler" would be a whole other thing. And I take seriously, the advice about not lugging the engine or using the drivetrain harshly.
I have an EZcarlift because I have a low ceiling garage where I park the 3 Morgans, can easily move the lift under the cars. It is one of the best tools I have bought, very versatile (I use it for servicing my Snowblower and as an outdoor work bench, etc.), moveable and transportable, can stop it any height within in its range, plenty of space to work underneath and very stable. Of course it is not essential to have a lift but I find it extremely useful and saves my back. If you enjoy your Morgan like to learn about how things work and are willing to get your hands dirty then ownership can be very rewarding and fun. A great many of us are not engineers or car buffs and have learnt how to do things from sites like this and the general car community, the "how to do it" is pretty much all online with videos it's just knowing where to look and as Craig says patience.
