I am wondering if some one can tell me what would cause my primer bulb to collapse so bad that it is flat? It all started with me troubleshooting a problem with my RPMs jumping up and down. I have replaced:spark plugs, water separator filter, fuel pumps, rebuilt all three carbs, primer bulb, hose and connector from motor to fuel line adapter that runs to the water separator. I also cannot get my buzzer to come on when i turn key to pre start position.Tried jumping the pink and black wire on motor from sensors and have nothing. There is a set of 3 wires near the control box that have a pink and black along with i think a yellow that are plugged into a dummy outlet that when i jump the pink and black i can get a buzzer. Any help anyone?
