Weed Eater issue?
Sooo I know this is a Ford forum but somebody has to know. I’m trying to help my nephew.
Weedeater brand string trimmer. First it would not start. Gave it a squirt of starter fluid to see if it would fire. It did but quickly died.
So I took apart the carb spayed it all out. Replaced fuel line primer bulb and fuel filter. Put fresh gas in it. Followed the instructions it fired up ran for 15 seconds full throttle died. It would not start. I gave it a quick shot of starter fluid fired died would not idle. Full throttle fired ran for a few seconds choked died. Now it won’t start at all. Im thinking the carb is going / gone bad.
Tested compression out of curiosity. Tested out at 75 psi. I read anything above 60 is good on these small engines. I’m 99% sure it’s a fuel problem. If it was a spark issue it would have not fired. However I tried to spark test it and could not see any spark. I may not be doing it right.
Anyway what’s next? Replace plug try to adjust carb?

Verify the does the engine produce suction on the inlet? It's common for the rear case seal or the front crank seal to go. Without that a two stroke won't run. If this is running a walbro carb don't bother cleaning it just replace it. You can't clean the internal passages. Good news is the clone carbs are below 15.00 now.

I’m going to just replace the carb. How do I check for suction? I used a compression tester and it tested our right at 75 psi. I read all kinds of things that it has to be at least 60 psi but then other sources says way higher.
Also I spoke with a small engine mechanic. He told me that this was a “50 hour” engine. Quoted the emissions sticker. He said it’s not worth fixing. That I should trash it. He went on to say stuff about the emissions ratings and all the equipment he sells is whatever 100’s of hours rated. Now maybe some truth to what he said. But I felt like it was a sales pitch.
I’ve got a 27cc craftsman from about 7 years ago it’s got the same 50 hour rating, I definitely have way more time than 50 hours with it. Runs just fine.
Any truth to what this person told me?

2 stokes carburetors have a short life. They're too cheap to even bother cleaning. For less than $20 you should be able to find one on amazon straight from china.

I sold and repaired trimmers, ect., for quite a few years during one of the many enterprises of my life. Weed Eater trimmers have always been like a Bic lighter. Run them until they quit, then throw them away.
75 psi is low.
75 psi is low.

I’m going to try to work on his other string trimmer. This weekend. It’s a STHIL. I’ve not messed with it yet. But it’s not running at all either. What psi should you expect from an operational Small 2 stroke like these engines?
Thanks.

No much you can do on the cheap engines. They mostly have a single ring pack and have no chrome cylinder bore. You will have better luck getting the Stihl operational and parts are definitely available even for the older ones.

Stihl chainsaw parts are available for cheap on ebay but not their other stuff. I wanted to fix my stihl leaf blower and the parts were more than half the cost of a new one. And I couldn't find any Chinese parts, only stihl parts from a distributor.

Weedeater issues are a total pain. I've had a Husqvarna weedeater for 15 years or more & only replaced a fuel line & filter once & about 4 trimming heads. Still runs strong, I love that brand. I also have a small stihl that wife uses & it's been around about 5 years, works great but Husqvarna has proven itself to me. Good luck with replacement.
