Question about Homelite Mighty Lite Lawn Trimmer

1 Answer

My Homelite Trimlite trimmer will only run (idle) in full choked position. You pump the ball, switch on full choke and it will start and idle. Can not give it any throttle or it dies. Cannot take it off of full choke, period, or it dies!! Could you please give me some ideas to try? I cant afford to take it anywhere....

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.

Could be a dirty fuel filter or cracked fuel line. The filter is usually inside the tank. You should be able to take the cap off and turn the unit upside down and shake it so that the filter drops from the tank. If not then grab it with a pair of needle nose pliers. If changing the filter or replacing the lines doesn't work, the carburetor might need to be cleaned.

Fuel starvation either too the carb or in the carb itself, start with a simple cheap fix, replace the fuel filter in the tank on the end of the fuel hose.

If it only runs with choke on, then mixture is too lean or idle set to low.
Adjust mixture initially at 1.5 turns, then move in or out as needed for highest idle when warm.
Make sure no leaks or clogged filter when adjusting.

Hard to say with string feed, but are you sure you are not putting the spool in backwards?

Correct start proceedure


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

My homelite string trimmmer will not run when choke is run position. it will run, but not at full throtle, when choke is set between full choke and half-choke.


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

These 4 cycle trimmers need to be primed 10x before a cold start. The bulb will feel *firmer* on the last two or three depressions and you'll know that the carb is primed.

Full choke and and full throttle on first tug should see it hit once with a puff of smoke. Second start attempt should be in choke position two (half choke) and with full pressure on the throttle. Should rev to life on start attempt. Let the engine IDLE for 30 seconds, moving the choke to off at the end of the waiting period. Let engine idle to warm another full minute with no choke, then set to work!

Trimmer will only run in choke position


You have a few possibilities. Make sure you have good fresh gas in the tank. You're not getting enough gas, so choking helps get more gas than air, making it run better. Could be the carb diaphram (not very expensive if you replace yourself), when they get old they don't perform like they should. Could be the filter in the gas tank is bad, plugged. Also might be just an easy adjustment on the carb Low, and High speed screws. The choke has three positions, full choke, partial choke, and no choke, which means run position.

Problems with my HomeLite UT20760 bogs down, no power


try this
you need to locate your muffler and find screws that remove a screen behind a plate you can remove on the muffler or behind the muffler itself
This screen is a spark arrestor screen and needs to be cleaned and put back or some would say discard all together, but i didnt say that.
give it a look see
this may be your problem and maybe not?
if it was you will see a trmendous difference afterwards
