No start string trimmer

[Whimsey]

I have a no start Ryobi CS30 string trimmer. It worked great for years then I had problems starting and if it did it would eventually stop running for no obvious reason. I replaced the carb and even the ignition coil as well as a new spark plug. Once in a while I could get it started to run for a few minutes, but not usually. Also the fuel tank and lines are new. The other day I got it to start after dozens of pulls. It ran great for a brief period but it stopped and I could not get it started again. This engine is not rocket science but I have to admit I'm stumped. It's been a personal jihad to get this working but I'm afraid I already put more money into it than it's worth. Any advice? My Harbor Freight spark ignition tester shows that there is a spark upon cranking.

Have you cleaned the exhaust yet?

Or adjust the carb

Yeah the spark arrestor can get plugged up. Happened to my homelite gas trimmer. Check the fuel oil mix. I have added slightly more oil than required and found that this can happen.

Does it have fresh gas in it?

Add a 1/4cup of seafoam and try again.

It's dirty gas/oil mix, carb or exhust and maybe a plugged up air filter. Go through those. Try YouTube tutorials but don't be afraid to tear things apart can clean everything.

In addition to all of the above, I would also do a compression check, just for a point of reference.

Go for a cordless and forget the issues with a 2-cycle engine.
