Check air filter if dirty clean with mild soap and water let dry apply very thin ammount of oil ( any type will do) to sponge type filter put a rag around filter squeeze excess out replace filter. Check spark plug clean if dirty, check electrode in center of the plug if rounded it should be replaced, gap check according to specifications. check ceramic filter in fuel tank if installed, if so empty fuel carefully remove filter by hlolding line and filter. Don't let line fall back into tank. find somthing to hold it so not to damage line. Or ask a friend or family for a hand clean filter with carburetor cleaner, replace filter. fill tank with proper fuel mixture. Good luck! Happy trimming!

How much oil do you use? in the mighty lite


Homelite Mighty Lite engines require the gas/oil ratio to be mixed at 50:1. That is 2.6 ounces of oil per gallon or 1.3 ounces of 2 stroke oil per half gallon of gas. I recommend using synthetic oil. It lubricates much better, allows the engine to run cooler and smokes less.

I have a MightyLite weed eater - the plastic bobble has a crack. What are my options besides purchasing a new weed eater? Purchased at Home depot.


You don't have to purchase a new one. Parts for it are available. This online parts house is good. If you are saying you need the plastic bubble for the carburetor, it is here.
http://www.ereplacementparts.com/homelite-misc-parts-c-18807_24213.html
There are 3 models listed. They are listed in the 4th section of misc. parts and are items 9,10, and 11.
All the other parts for your machine are listed here too:

Homelite mighty lite wont stay running


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

Stalls out at full throttle


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

Homelite gas trimmer will not run without half choke and throttle


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.
