83 yamaha enticer 300 wont start. if i use starting fluid directly into cylinders it runs and dies

Put a new battery in it and add it to the price. ATV batteries are abused, they need a trickle charge if not used for a month. Expected life in a neglected state would be 3 to 4 years. Is it the original battery and 8 years old? Strip and clean the carburetor.

Remove air filter and spray a short burst of starting fluid directly into carburetor throat. Promptly start. If it runs for a few seconds and dies then no fuel from carburetor.

If it doesn't fire then, no spark, no compression, bad timing, or flooded.

You can test carburetor by removing the intake boot and spray starter fluid directly in to it while reving it up. If it revs up then, clean the carburetor reservoir tank and jet holes(this are usually very tiny holes in the carburetor's body

spray carburetor cleaner (NOT STARTING FLUID) directly into carburetor if it runs for a few seconds if so carburetor needs cleaning and if not a rebuild done

If the fuel pump IS working, and it runs on starter fluid. then the carburetor float may be stuck or the jet is stopped up.

If it has been sitting to 6 years then the gasoline is no longer any good. Drain the fuel tank first thing. Remove the float bowl from the carburetor and drain the fuel and clean it out. Put in fresh fuel and try to start it. If it still will not start try using starter fluid to see if you can get it going. You may in the end have to disassemble the carb and clean it out.

Well you didn't specify what kind of motor it is just that it's a 1994. If it runs when you use starting fluid but dies then the problem has to be fuel. I'm assuming you've changed the fuel filter. I'm not sure what kind of an engine you're talking about here but if it hasn't been run for two years and it has a carburetor the float could be stuck. If it is stuck in the up position this would block fuel from entering the carburetor. Check it, the fuel filter and the line coming from the tank and trace the fuel supply all the way to the engine from the tank.

I'm not absolutely positive, but the pieces you speak of sound like a cushionbetween the lever and cylinder.---- Piece,-spring-Piece------ It acts as a cushion and assure clutch cylinder is actuated with
enven and aligned thravel so the pisto is not subjected to side pressures of the lever movement. Good luck and happy trails. They wou;d fit between the lever and cylinder like a flexible push rod.

Springtime start ups after sitting up for awhile can be a problem. You have nothing to loose, spray some starting fluid into the air cleaner. That may be just what is needed for an easier spring start.
