I just took the pulley off a self propelled super 21 like that, after 35 years it was rusted solid on there and the only way to rewmove it was to cut it off in that instance.
Be gentle with the fuel tanks, I have several leaky ones and no good ones at all, one cracked around the welds that hold the mounting bracket on, one was weeping around the edges and the other had an obscure leak I cannot recall.
No need to remove the points, maybe if you were fitting it to a kart or something and wanted to go extreme on weight reduction it would matter otherwise they will just sit there and not affect the engines running.
