Well, I definitely did not have any such problems with my 8448, so my
guess would be that some gear or other is blocked somewhere. Have
another go.

Agreed. I remember my 8448 as being very smooth when it was built, and I was
able to motorise it using the older 9V ungeared motor no problem. If my
memory is correct I geared the motor down by 9:1 before the gearbox, and it
would even start in the higher gears, just as long as it was on vinyl at the
time! I remember being pleasantly surprised by the power of the motor, as
the only previous similar experience I had had was trying to move the 8860
with the old 4.5V motor, which moved like a slug on tranquilisers, as they
say...
