When using starter fluid, remove air induction to the throttle body and spray a 1 to 2 second burst directly down the TB and promptly start.
Also a flooded engine will not fire, even with starter fluid. Pull a plug and see if it's soaked with fuel. If the plug appears dry and there is spark and it won't fire on starter fluid directly down the TB, then most likely the spark is too weak. Inspect cap and rotor for erosion. Look for signs of carbon tracks on the cap and the coil.
if it was the fuel pump engine should start with starter spray at least for a second or two, so, it sounds like your fuel pump is bad.
turn ignition to run and try hearing the pump run.
Try a tiny spray of Starter Fluid in your machine. If it runs for a second then dies,,,, it would indicate that you have a Fuel problem. Broken gas line of gummed carburetor. Ethanol gas is known for ruining both gas lines and carburetors.
Are you pulling the plug to check for wetness after cranking it a few times, WITHOUT using the starting fluid? Also, I would recommend using carb cleaner in place of the starting fluid. Starting fluid runs the engine VERY hot for a brief time and can possibly damage rings, valves, and aluminum parts.
remove and clean the carby. clean out the main jet. ensure that there is nothing stopping the primer circuit from working. There are two valves under the primer bulb and a spring. when you push in the bulb fuel is squirted into the manifold When you take your finger off the bulb the spring pushes it out and new fuel is drawn past a valve to fill under the bulb. Pushing in again closes that valve and opens a second valve which allows the fuel into the manifold again
It could possibly be a faulty Crankshaft Position Sensor. If the computer doesn't see that the crankshaft is spinning, it won't activate the fuel pump.
Put somebody with good ears under the gas tank. (the fuel pump is in there). Switch on the ignition, but don't start. The pump should run for 2 seconds. You can hear it.
If it does run, change the filter.
If it doesn't run check the relay under the center of the dashboard for operation and power in and out. You may have a bad pump or plugged up in tank screen..
siphon out the old fuel and put brand new fuel in the tank. Change the air filter even if it looks ok. Put in a new spark plug. Then get a can of starter fluid and an assistant. Squirt some starter fluid into the air intake and start it up. have your assistant continue to spray the starter fluid for a minute or so until it runs on its own. J.
Hi, The carb is gummed up from sitting. The best solution is to take it apart and clean it. The starter fluid indicates that it has clogged jets or stuck floats. The good news is that if it cranks with the starter fluid everything else is probably OK. Good Luck!
