Question about Garden
I have a Yamaha EC5000DVE THE ONLY WAY I CAN GET IT STARTED IS BY USEING STARTING FLUID
Is there any chance that this generator sat with fuel older than sixty days in it?
All gasolines, including non-ethanol, are organic. They will encounter chain phase separation if not treated with a reputable stabilizer. They fuel simply breaks down over time, and it has a very short shelf life.
Fuel that contains ethanol is even worst when untreated. The alcohol in the fuel will draw moisture from the air. Over time, it will accumulate water in the gas storage can, fuel tank, and carburetor, causing corrosion inside carburetor components. This is what I suspect from the symptoms you describe.
This carburetor needs to be disassembled and thoroughly cleaned. The float is probably stuck, and there is a chance that the mixture screw (if equipped) is clogged with corrosion or foreign matter.
If it is possible to remove the mixture screw (sometimes the plastic limiter caps can be easily pried away), be sure to notate the orientation of the screw. Then close the screw until it barely seats, carefully counting the turns. Add this number to the notes, and it can be replaced later to the exact position.
I used a thin piece of wire to clean a badly corroded Honda carburetor once the mixture screw was removed. The wire was used to scrape back and forth through the hole at the end of the seat (it could be seen protruding into the carburetor bore). The screw was lightly scrubbed with a wire brush. The entire carburetor was cleaned with non-flammable brake cleaner, focusing on the float and inlet needle to be sure they moved freely, It started in 4-5 pulls.

Has it always done this or has it developed?
Some saws have a decompression button to make it easier to pull over.

Yes, it is possible that the spring needs to be pre-tensioned. its also possible that something was put together a little out of alignment, or some part is too tight and its too hard for the spring to wind in the chord. try to reassemble the chainsaw with a couple more turns on the spring and see if that helps.

I think someone failed to put oil in the fuel.
Determine if the warranty is active first. Most warranties are effective for 1 to 5 years. If yes return it to where it was purchased or find an authorized repair facility. A written diagnosis by a good independent saw shop ($10-20) might be a good idea at this point. It is difficult to argue repair charges with an authorized repair facility without some documentation in your favor.
1. Remove the starter housing. Does the starter operate smoothly? If yes, reinstall the cover and continue with 2, if no repair starter.
2. Is the saw equipped with a decompression valve? Yes continue, no proceed with 3.
· Leave the ignition off, set the valve and pull the starter.
· Pull gently to release the valve. Is there a difference in the effort required? If yes continue with 3, if no repair or replace the decompression valve.
3. Was this saw perhaps operated without oil mixed with the fuel?
· Remove the spark plug wire and plug.
· Remove the muffler, hold a light at the plug hole and inspect the cylinder through the exhaust port. Is it smooth and shiny or does it appear speckled with dull gray spots or smears?
· Pull the starter slowly, inspect the piston as it rises and falls. Is it a dull gray without scratches and gouges?
· Hold the light at the exhaust port and inspect the cylinder, above the exhaust port, through the spark plug hole. Is it shiny and smooth or speckled with gray spots or smears?
Any spots or smears on the cylinder or deep scratches and gouges in the piston indicate the saw was operated in a lean condition. Repair of this on a home owner quality saw often exceeds replacement cost. A repair estimate by the independent saw shop should be considered.
4. The final likely possibility is the saw has jumped timing. This problem or any not discussed is usually beyond the ability of the operator to repair. Please take it to a good local saw seller/mechanic for a written diagnosis before authorizing any repair. HTH

If someone put the wrong sparkplug in the saw it would do the same thing. The plug threads could be too long and when the piston comes up it hits the plug and stopps. If the electrodes on the new plug extend farther out of the sparkplug the piston will come up and hit it and the engine will not turn.
