    i have cleaned it and have also cleaned the carb. thanks for the response back.

    it will run when at half idle and if i squeeze the trigger at half it will slowly run up. but when i close the choke it dies. exhaust doesn't seem any different than before. i didn't touch the screws, the only reason i pulled it off to clean was to fix the problems hopefully. i cleaned the exhaust port as well. put it all back together with some hope and it still did the same thing. at wits end now.

    I would try adjusting the air/fuel mixture screw -- even tho you didin't touch it, taking the carb off could have created a need for adjustment.

    Well, this is a classic not getting enough air or fuel issue.



    Does it run long enough to detect any difference in the color of the smoke versus the color it was when it ran well?



    Did you change the air/fuel ratio screw setting while you were working on the carburetor?



    Did you clean the carb because of this symptom or was it just routine maintenance.

    Have you cleaned the air filter lately?

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

Electrical:
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 Butterflies
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.
("Operator Error")

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 cuts off when i squeeze the handle on the sprayer, what is causing this to happen?


Sounds like a bad unloader valve. Do a search on "pressure washer unloader valve symptoms". When they are faulty there will either be little pressure or it will stop an engine abruptly. The engine will not just die down as it you were turning it off. It would stop cold.

What is the gas oil mixture for homelite sx135 trimmer


Use 32:1 with good quality 2-cycle oil. I have Used Stihl, Homelite, Poulan and Several Other 2 Cycle Trimmers in the Yard Maintenance Service and Have Found the 32 to 1 Mixture to Extend the Life of the Engine. Always Remember to Drain the Tank and Run the Engine Until the Carbuetor is Empty for Off Season Storage.

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.
