I have a Ryobi straight shaft trimmer. Have had it probably 10 yrs. Bulb finally cracked, so no problem, put a new one on. Worked fine, but just wasn't what it once was. Did what y'all recommend, get a new carb. Ordered from Amazon. Put in on and running good. However every time I go to use it I have to fiddle with it and I'm tired of that. It might run for a few seconds or maybe just pop off. Think I got a crap carb? The whole thing was only $100 new, so hate to throw another $30 carb at it. If I do, any good places to get one?

It does have new spark plugs, fuel lines and fuel filter.

Cracked bulb might have shed bits that entered old and new carbs . Clean out and new fuel lines and tank filter first .

Pastdeere,

Check the armature gap, set it @.012.
Check the muffler screen. If clogged, light it up and brush it off.

Empty the fuel mix, and put it fresh fuel mix.

Gap the plug between .025 to . 030. Then go do some weed wacking,

Guido.

That's why I bought a Ryobi battery one last time.
Quiet and very light weight.

Exactly my feeling, my 40 volt Ryobi lasts a long time on a full battery. Don't have to crank for 10 minutes to get it started either.

Yeah, if I only did the yard, then maybe. But I take it to the rentals and it needs a little more beef to get the job done.

Does it have a yellow shaft? if so it is Homelite product. They're junk.

The really old silver-shaft Ryobi(s) were pretty good units.

Then MTD got a hold of Ryobi and worked their magic and from then on they were only 2-3 year machines at best. About the time the warranty expired, its time to get another trimmer.

It could be a bad carb. I've run into that with the China replacements, need constant main jet adjustment to keep it running.

Been fighting that on a Stihl pole saw, next move is to buy a carb from Stihl.

Been down that road a couple of times. Seems like most carbs (at least the cheap ones). I've had instances where I had to go to a second replacement and it worked fine.

Multitasking - meant to type that the cheap ones are Chinese. I've tried them on non-critical stuff due to the price and have had okay luck. However, I have gotten bad ones and had to rinse and repeat.

Yep. Replaced a silver shaft one after it went crappy. The silver one was fantastic. Never been a fan of the yellow one. Might go Stihl.

80v kobalt works great so far. Easy to start.

I bought a new carb for around $15 off of either amazon of ebay.
That's when I discovered my 4 stroke engine was a honda. It's a few pounds heavier than a 2 cycle. If you ever use it you will say that's the most powerful weed wacker. The boss doesn't want a battery powered one. She likes the husky-varna. Very easy to start. Very powerful straight shaft, 2 string trimmer.
It's a lifetime trimmer if you change the oil.

Fuel lines get old and split too, air get sucked in with the fuel and the engine runs too lean. Ten years out of a set of fuel lines is pretty good, they are due for replacement.

Try taking the reed valve out and check the plate that limits how far the reed valve opens, I had a Ryobi and that plate was bent so the reed valve wouldn't close properly.
