Sorry for posting this here but this group has always been helpful. If you know a better group please tell me and I'll post it there.



I have a 25cc Homelite weedeater that is about a year old with little usage. It suddenly will not "get up to speed" It will idle perfect, starts very easy, It is just when you try to give it full throttle it boggs down. I have cleaned the spark plug and air filter.(they looked good) I started to adjust the carb but it was running great yesterday and it still idles perfect. Any suggestions as to what is causing this. I even mixed up different gas just to make sure the gas was fresh.


Sounds like it's running lean.... probably got some crud in the high speed needle. Gently close the needle, count the turns so you can open it back to the same setting. Sometimes that will break up the junk so it passes through. If it still won't run right open it a little further. Two stroke engines are pretty touchy about the mixture. If it bogs down and wants to stall it's probably lean, if it keeps running but has no power it's probably rich. Bob

Yes, and FYI. It most likely has 2 mixture screws side by side. One for idle, one for high speed. play with the high speed one....

It was the muffler screen. (spark arrester) It was clogged.

Darn. Should've seen this post sooner. I had a Homelite weedeater do the same thing. Turned out that a mud wasp had built a nest in the muffler. Once he was evicted and the thing was cleaned out, it ran fine. Scott snipped-for-privacy@aol.com
