Question about Homelite Mighty Lite Lawn Trimmer
It will run until I squeeze the handle to use it. Same problem KenniBoy posted. Every time I squeeze the trigger, the engine slowly dies.
This can also be (just did this too with my Zip Start):
1. Nasty Carb (loose screws or just funky)
2. Leaks (be they Air or Fuel Gaskets!)
3. Funky Exhaust Port
4. Fuel (check it ALL, lines, filter, tank)
5. Fuel CAP (believe it or not, they ARE vented for a reason, to PREVENT Vapor Lock)
6. The Spark Plug (if it is weak, she will act like that on the High Side, sometimes, even when Idling nicely! Double check your Plug Seat as well, where the Plug meets the Cylinder Head, if it is funky bad, clean it up, a good ground is a must!)
Remember that on a 2-Stroke, Spark Plugs take a hell of a beating on heat, or getting over-fueled (which they do, when carbs are unmaintained). And UNLIKE 4-Strokes....they have to burn OIL too! (Foul faster)
Fuel -> Fuel Filter-> Fuel Line-> Carb->
Splits here into TWO paths:
1. Fuel Bulb-> Fuel Line (Return Line)-> Fuel Tank
2. Fuel Bulb-> Carb-> Intake Port-> Piston-> Exhaust Port-> Exhaust Port Screen
Magneto-> Rotor Magnets (for Spark Plug, AKA- Ignition)->Spark Plug Wire->Spark Plug->Cylinder Head
Kill Switch (grounds all the above to the cylinder)
Running: (Carb, etc.)
Throttle Cable (super simple)
Carb Seats, Carb Gaskets (air leaks/fuel leaks)
Needle Seat (Fuel Flow, Gummed UP!)
Any and ALL Fuel/Air Ports in the Carb.
Fixes: CLEAN THE CARB. I don't mean spray some WD-40 on it and call it "clean". Tear it ALL the way down (CAREFULLY!), and put her back together. Use some compressed air and Gum-Out.
NOTE: "Gasket Kits" are NOT a fix EXCEPT for leaky GASKETS!
They do NOT fix 99% of the problems: Spark Plug or Dirty Carb!
They will NOT fix "Operator Error" either!
NOTE: If it requires fuel (or a mix), it will invariably get gummed up, and nasty. Carbs are about the #1 reason ANY small engine fails, and ONLY second to people who will....not....maintain...equipment.
NOTE on Carbs: If it worked brand new without an adjusted carb (factory settings), it does NOT need adjusted now. What it needs to be is CLEANED, and put back into service. E.G.- MAINTAINED!

The engine is not getting enough fuel to the high speed jet. The issue may be one of the following:

After checking the plug (absolutely clean!), and the carb function, and the air filter media several times, I finally noticed two buttons on the inside of the air fliter housing, and discovered they were NOT aprt of the plastic housing, but rather were built-up dirt, mixed with oil, right at the air intake! I cleaned them off, and now it runs like new (even with old gas)! So it turns out it was starved for air, not fuel. Often the simple fix is staring you in the face, and you don't see it because you're looking for sonething more complex. Thanks for the other opinions.
