Another fascinating video. I love that you spend so much time focusing in and around the engine bay. So many parts such as the carburetor, starter switch and regulator are the same as you would find on a variety of British cars from the fifties. Austins, Triumph, Morris all shared the same ancillary parts
Of course my suggestions are after the fact, but here goes. Ive had better results with the WD-40 vs the grease when installing the rubber components. An alternative is baby / talcum powder. Mercedes recommends the use of talcum powder on the rubber gaskets around the door frame, trunk lid etc. Narragansett Bay
Next door neighbor had a couple of these back in the early 70s. He tried to put a Chevy 283V8 in one of them, huge back tires. He couldn't keep it on the road!!! Too much motor.
I was wondering why a guy that is 6 foot 14 inches tall would decide that he just had to fix up and drive a Metropolitan! LOL 😆. Love that little Met, it is just like the one that my high school German teacher drove.
