Lister petter tx2

[Olivax]

Hi guys, New to the forum. I have a lister petter tx2 in a site dumper, was running fine then cut out, chased fuel to the two fuel pumps.
Removed the two inspection covers and it seems the links for the pumps have disconnected from the stop switch (think it's the governor) is there a way to connect the link to the Rod without stripping the engine down?
Trying to get my fat fingers in through the first inspection cover but very restricted access. Hoping someone will tell me I've missed something very simple.
