adjust the high speed screw first with the throttle at full speed, then adjust the idle screw to maintain idle speed

Your carb high and low settings may need tweaking if it's not a fuel or muffler issue. I believe needles are made only to be adjusted by a technician. If you want to try adjusting it yourself, google and you tube your to see how.

OK! You know if you put fuel in it runs. You have replaced the fuel lines and filter which is great too. What is left? Two things....

1) fuel inlet screen inside the carb.

2) diapragm lever arm clearance.

Both of these are under the little covers on the carb. The one with four screws is the diapragm. The other will have one or two screws which is the inlet screen side.

Remove the gas from the vac and proceed to take the fuel inlet cover off.
The cover is under the air filter body so you have to pull the two star head screws out to get to it. With the fuel inlet cover removed you can pick out the screen inside the round hole and check it for debris/gelled fuel. These things plug at the drop of a hat! You can either try to clean the screen or go to a parts store and pickup a fresh one. I would go with a new one since the screens are so delicate cleaning is almost impossible. If you hold the screen up and look through it you will understand what I mean. You can also look on Ebay and order one and get it by mail. Which might be easier and still cost effective.

Once you replace the screen *(you put in the new by setting it in the hole and gently pressing it in with something blunt and about the size of the hole. It wont take much effort so be gentle. Once the screen is in put it back together, add a little fuel, and check the primer for rebound.
That is to say that the primer , once pushed in, should come back out quickly and fill with fuel. If it drags or stays in you still have a block somewhere in the system. This might mean removing the carb and stripping it completely and cleaning all the passages.

Do the screen thing first and we can discuss the diapragm work after that. Here is a link to homelite too:

Question edited for clarity and spelling.. Please don't type in all CAPS, it is classed as SHOUTING and harder to read. There is no wiring diagram for it online. It is just a mains lead, a switch and a motor. Parts schematic and a link to the company support. https://www.google.com/search?q=homelite+lawn+mower+ut13124+wiring+diagram ..

The fact that is runs slightly longer on full choke may point still to a fuelling issue.. Does it actually Rev in those 10 seconds or does it just want to bog down and stall.?

Is it in the right way? They only work in one direction. They can also be faulty from new.

You should have 2 lined coming from tank. A return and feed. Normally the return is the lowest positioned outlet on the carb, and the feed is at the top. When pumping the purge bulb take the gas cap off tank, and you should see fuel being returned to the tank from the return line. If not, switch the lines on carb. If still not returning fuel to the tank, you will need to pull the carb and inspect the metering and fuel pump diaphrams.

The recommended spark plug gap for a Homelite 2700 PSI pressure washer with a Champion Eco 322 spark plug is 0.030 inches. but in my opinion, It's always best to consult the owner's manual or contact the manufacturer for the most accurate and up-to-date information regarding the proper spark plug gap for your specific pressure washer model. good luck

Champion RCJ-6Y or NGK BPMR7A spark plug with .025 in. electrode gap.

The recommended fuel mixture is a 50-to-1 ratio of unleaded gasoline and two-cycle engine oil, and the manufacturer recommends the use of a two-cycle oil that contains fuel stabilizer to keep the mixture fresh if you are not using it immediately.

You need to clean out the carb. possibly replace the Needle Valve and check the Diaphram for stiffness. Also check the fuel line for cracks and rott.

GAP: 0.025 in. (0.63 mm).

Want to give us a hint as to what kind of weed Eater this is? Most gas models use a mixture but the ratio can vary between manufacturers.
