Weed Whacker: Weed wacker runs fine but stops as soon as it hits the grass

Wed, 07 Jun 2023 13:14:48 -0700

I have an older model 4 cycle craftsman weed wacker probably around 10 to 12 years old. Have replaced fule line a few times and even the clutch once or twice as well as cleaning the carb here and there but at the end of last year I went to use it and it started fin reved up to full then as soon as it took a load by hitting grass shut off. It then started and reved fine again and did the exact same thing like 5 times in a row. I have a smaller one that I have been using but I have a bunch of attachments I really need the power of the 4 cycle for. Any idea on what could be wrong?

Echo SRM-225 Trimmer: Will not start after running?

Fri, 02 Jul 2021 06:46:24 -0700

So, really weird problem… I have had this Echo for 15 years and it has been great. I have ran it to death. I have always been able to fix it but this problem has stumped me. The thing will run perfect. It starts on first pull. Then it will shut off after 30 min and it will not start again until it is completely cooled down. I am talking completely cooled down. I will need to wait up to 20-30min to start it again. Things I have down:

new carb
new hoses
new air filter
new spark plug
new gas
added more oil than normal

Thank you for your help.

Echo SRM-225 Trimmer: Echo 225 Trimmer won't start. Tried all the basics

Fri, 30 Aug 2019 09:00:53 -0700

Purchased a used Echo SRM 225 that won’t start for nothing. This is what I have done so far.

Put in a new carb, new air filter, new fuel line and filter and a new spark plug. Also new gasoline 50:1 mix

Checked the ignition coil and the new spark plug for spark. Also checked it with the ground disconnected.

Disconnected the off/on switch to make sure it’s not that.

I have not checked the compression but have a new piston ring and cylinder gasket that I have not gotten around to changing out. I do smell gas from cylinder when trying to start but have not checked the inside of the cylinder for scarring. I did check the piston by removing the muffler and the piston appears to look fine with no scarring.

I will also be cleaning the spark arrestor when putting on the new piston ring.

I’ve worked on quite a few different trimmers with success but this one has got me stumped. I’m running out of options and do not want to put any more money into this.

Any other suggestions would be greatly appreciated!

Weed Whacker: Echo SRM 225 will not run

Sun, 12 Aug 2018 08:31:45 -0700

I have verified carb, ignition, fuel lines, air and fuel filter, plug are all good, compression is 50 psi 1st pull, 75 psi on 2nd pull, and 90 psi on the 3rd pull on the starter rope. I can get up to 110 psi by 6th or 7th pull. It will hold the pressure for a hour with no leak down. Please tell me what I am missing.

How can I adjust the idle speed up? It Boggs down when I release the throttle and stalls. Also when starting I must have the throttle up to full or it won’t start. When running I can’t move the choke to run it must be kept on half choke. I need to know how to adjust the idle up
