I am working on a 2005 Yamaha 40 horse 2 stroke. It runs great but is hard to start. I am looking at the primer device located on the middle carb. I checked the blue wire for power when the key is pressed and I get nothing. I removed the primer and went straight to the battery with the blue and black wire and the plunger doesn't move. I don't change parts until I understand the problem.
Should the plunger move when the key is pressed? Is there an automatic mode for this thing? Thanks for the help.
