I have owned this trimmer for a while and it is getting hard to start. Replaced the plug and cleaned carb although it was real clean inside. I have to spray starting fluid to get it started and then it runs great. Wonder if a different kind of plug would help it to start easier? I like the trimmer but my shoulder is bad and I can't pull on it 10 to 20 times to start it. And then when its warm it can be hard to start. Makes no sense.

Is primer bulb pulling in fuel? Was metering diaphragm soft in carb? Fuel lines and fuel filter good? Might want to check valve clearances.
Link below is the operator's manual

New lines bulb and filter and it is sucking gas good . I might get a carb kit and try that. Once its running it runs great its just really hard to start.

check the spark arrestor screen in the muffler for being clogged
(clean with a wire brush and maybe a little gas or carb cleaner.)

If you press the primer bulb a few more times than what you normally do then does it help startup. Looks like only one adjustment on carb, might try bumping idle up just a little. Not enough for trimmer head to start trying to rotate.
