Hello Tim,
I have had a simular problem with my 1987 Morgan. In cold condition it
was no problem at all to start the engine and as soon as the motor
became hot, it became very difficult to start the engine.
After some "trouble shooting" I found a "bad contact" between the cable
connection of the motor to the chassis. In the motor compartment near
the frontwheel you will find a cable connection between the motor and
the chassis (negative earth connection). Due to some bad contact between
the cable eye tag and the chassis (paint not sufficiently removed from
the factory) there was some resistance in the connection and as soon as
the motor became hot, the resistance increased, causing a drop of the
voltage of the battery resulting in a very lazy and very slowly turning
startmotor.
So, what you also could do is, to check the battery voltage as soon as
the motor is hot and the start motor is getting lazy. Incase you see a
drop of the battery voltage from 12V to 8 or 9 Volt, I would suggest to
have a look to a possible bad connection of the motor/chassis cable
connection.
To measure the battery voltage, I would suggest to use a "portable"
voltmeter, because the voltmeter of the Morgan dashboard has a very slow
reaction time.
After removal of some paint from the chassis near the chassis connection
bolt (to make good contact) and cleaning of the cable eye tag, the
starting problem disappeared and I have been driving trouble free for
over the last 9 years.
Good luck,
John.
