Miklos,
You might also want to see page 90 & 91 of Original Morgan 4/4, Plus 4 & Plus 8 by John Worrall & Liz Taylor. This has more detail.
I have a 1986 Plus 4 which I bought new from the factory and kept in the U.K. for about 28 years, using it when there on business and holiday.
Swapped out the old Bosch fuel injection for 1/2 half of a Ford Mustang Mega Squirt injection system about 5 years ago.
Having lunch here with my friend who has an 85 4/4 with the 2.0 liter engine and he just put Weber carbs on a new system as when imported to the U.S. it was converted to run
on Propane to meet U.S. regs at that time.
The Fiat twin cam is a great engine.
Good luck.
Tom S
