Got a new battery last year, but then didn't manage to ride (2v K100 1985).
Pulled the battery out yesterday and charged it. Bike cranks, plugs spark (opened and checked), but I think I have issues with the fuel pump.
It initially buzzed, but now seems to stutter.
Motor coughs a few times when the pump buzzes, but the pump doesn't seem to turn each time I hit start.

Where do I start?

Possible terminals of the tankconnector corroded.
Take male and female from eachother, the male terminals have X on top, slightly bend it a bit open.
Connect tank again and start ya b@stard
