Fuel/Oil Mixture

1. Use a quality 2 cycle oil and mix it to the OIL supplier's recommended ratio. Today I use Stihl 2 cycle oil mixed @ 50:1 in a Pioneer that I purchased new in 1980. There are no gouges or scratches on the piston or cylinder and I have no carbon build up on the piston top. The manual (on stone tablets) recommends 24:1. Over the years the mixture has leaned from 24:1 (Saw Recommendation) to 28:1 (Lawn boy mower recommendation) to 32:1 (Oil provider 2gal premium/8oz chainsaw 2-cycle engine oil - used for many years) and finally the last 5 (±) years 50:1 (1gal premium/2.6oz Stihl 2-cycle engine oil)
2. Any fuel containing ethanol is not good with chainsaws. Mix what you expect to use within a few weeks. Anything over 1.5 months old use up in a 4 cycle engine. HTH

Will it start if you pull the plug and spray starting fluid in the chamber? if so then I'll bet you have a blown diaphragm in the carb or a plugged fuel filter or a bad gas line. hope this helps. Jeepfxr

Check the muffler screens first. Then the spark plug. If not the case, then adjust the High setting on your carb. Prolly starving for fuel under engine load. If it is still a problem, Pull the carb and clean it.

Difficult as it takes two guys to pull it out? Have you tried taking the recoil off of the machine and pulling it? If recoil pulls easy off of machine then try rolling the saw over by hand. If the saw resists rolling over manually then you could possibly have a burnt up engine. Do you have to mix gas for operation

You must help us if we are to help you.

if you store it somewhere other than a climate controlled building , the changes in temperature can cause the oil to expand out of the saw a little each time the temp. goes up.

try some absorbent cloth

Most saws and other 2 cycle engines use 40:1 ratio gas:oil.

I would not expect yours to be different, unless it is an older saw made before 1980.

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.
