My Homelite Mighty Lite 26CS initially starts but only runs on full or half choke and eventually stalls in about 5 minutes. Will not restart untill it cools off. I did mix fresh gas ,put in new spark plug, Still no difference. Any suggestions???

try running on full choke until it warms up.

Sounds like a lean condition. Rebuild carb, replace fuel lines and fuel filter and you should be ready to blow the leaves.

Hello,
My name is Dane and I am going to help you solve your problem.
I don't know what homelite says, but I have found that this works well on any 2 cycle engine.
1. Push the primer bulb between 3 to 5 times.
2. Place choke on full.
3. Pull rope until engine fires once or starts.
4. Move choke to half choked position and allow to warm up.
5. When warm place choke in run position

If it doesn't attempt to start within the first 3-6 pulls, check your spark plug and make sure your fuel/oil mixture is correct.
I hope I've helped! Thank you! Dane

you've got a fuel system issue , most likely carb problem, if this a newer trimmer it will likely need the carburetor replaced or adjusted, also check for cracking fuel lines or signs of old fuel varnish in the tank

the problem is in the carburetor most likely, it may be cleaned and adjusted, if not it will likely need a new carb

I had the same problem. I took it to the dumpster and used my old echo that I purchased in 1986. The Homelite was 2 years old. My sugesstion is to dump it.

Has the air filter been removed, damaged, or the airbox not seated propelry on the carbs neck, this would cause it to run lean hence requiring the choke to be in operation all the time. Have you tried fresh fuel?? This goes stale after a while. I hope this is helpful, Ian

Start your adjustment by turning both screws (gas and air) all the way in and then back them out one and a fourth turn. Start from there. Hope this helps.

You need to disassemble the carb. and spray with carb. cleaner. If you need tips on how to do this, just let me know. You may need a new carb. kit as well, but we won't know that until you first perform the first step, or if the carb. parts are more than 3 years old. If they are, then go ahead and buy the carb. kit and replace the parts.

did you try fresh gas
