My wife & I just purchased a new house a few months ago and was given this used trimmer as a gift. It worked pretty well for a few uses. It would die after about 20 minutes of use. I would crack it again and have trouble but after a little while it would start working fine. I only use it about 20-30 minutes for the front and back yard.
Once the gas tank was empty I looked inside and saw the line was torn and there were small pieces of line in there. the fuel filter was not attached to it's hose. I'm not sure how long it was like that? I replaced the hose with a new filter and ran OK for a little while but would bog down and shut off.
I should also mention it would never idle right. the head was always moving and sometimes at a fast pace. I took apart the carb and used carb cleaner to clean it out. put everything back together and cranked it. It ran but ran very very rich. no low idle, head constant spinning and would eventually bog down and shut off. I was taking it apart again and noticed the filter on the side had a hole from when it was running really hot. The fuel line also came undone on it's own from the carb when I was about to take it apart and now need to replace that because it will not stay on.
I dremeled the metal surrounding the idle screws and adjusted it but now won't turn over to even adjust it.
My thinking is just buy a new carb. plenty of success stories on getting a new carb installed but would I need to adjust the idle settings on a new carb?
