Hi and welcome to FixYa. I am Kelly.
There are 6 model numbers with Mighty Light in the name:
UT-21506
UT-21546 UT-21907 UT-21947 UT-21566 UT-21967 They all appear to use this muffler: http://www.jackssmallengines.com/partslookupcart.cfm?arisku=308990001&aribrand=Homelite&arireturnurl=http%3A%2F%2Fwww.jackssmallengines.com%2Fhelp.cfm%3Fario%253dgetAssemblyCollectionariamparipa%253dAnjgY*mKGXmndGJGQbyJww%253d%253dariamparica%253dwBQND3HPqCdAJrT8YcDNyA%253d%253dariamparioem%253dVOGGWB2rODFgBxRc4uyLwQ%253d%253dariamparit%253da439d57a-1a88-41c6-a006-f87871a54b42&ariqty=1 If this is not what you were looking for you can go to this site and find your model number. Just note that homelite engines are usually in the 2nd drawing of each unit: http://www.jackssmallengines.com/help.cfm Choose parts search by model (Folders) Homelite Homelite (again) String Trimmers Then search for your model number The engine is under general assy. It is replaced by simply unscrewing the mounting screws / removing the muffler and then mounting the new muffler using the original hardware and reverse sequence of removal for gaskets and heat shields. Thanks for choosing FixYa, Kelly

Remove the Torx screws holding the rear cover on. Then remove the larger Torx screws holding the muffler on to the exhaust port of the cylinder. There will be a gasket there. The spark arrestor will be mounted in the opening to the muffler. You can scrape or burn the carbon off of it. If the spark arrestor is real clogged up, then the muffler probably is too. It should also be cleaned. The inside of the engine probably is carboned up too( if arrestor and muffler are). They all should be cleaned of carbon. It helps the engine perform at its' best and breathe like it needs to.

Homelite trimmer, gas, string - y is the string wrapping itself around the head of the trimmer?


The line on my new 26cc Homelite would also feed out by itself. That started me thinking the line was wound backwards. I wrapped the line in the opposite direction as was shown on the bump feed reel and now the dang thing works although the bump feed needs to be "bumped" pretty hard to work. Is it possible that the reel was manufactured with the (string direction) arrows pointing the wrong direction? The new 26cc unit is also underpowered compared to my older 25cc trimmer.

My ut20811b string trimmer will not rev up to hi speed


Are you using fresh fuel with proper mixture.? If so, then there is two possible causes. Depending how old the trimmer is, the SPARK ARRESTER screen me be clogged. The other cause is loss of compression. Unfortuntly, this requires a tear down to find out.
