Okay, I'm stumped. Primer bulb will not pop back up and trimmer only runs for a few seconds when I put fuel in the air intake. If the bulb was cracked it would pop right up but wouldn't pump fuel. The only way to get the primer bulb up is to temporarily loosen the primer retaining plate screws.
Full gas tank, fairly new fuel lines, about a year, look okay. Filter/weight is attached to the pick-up line. I noticed a few weeks ago that it seemed like it was leaning-out and hard to start. Now there is no way to keep it running. I have a needle valve tool and even with both valves 3 turns out, it is not pulling any fuel up. But with the fuel manually put in, it starts and runs fine until it runs out of gas. I'm just about ready to go get a new one because I have all the extra gadgets for it and was getting ready to use the trimmer head, hedge trimmer and blower today. So I have to get another Ryobi so all that stuff fits.
Any ideas?
