Engine Starts with starter fluid, but won't stay running

I just purchased a Billy Goat Brush Mower on craigslist for a great price. I was not able to start it when purchasing it due to a missing fuel line. I got it for so cheap it didn't matter if it worked or not. After tinkering around for a bit, I was able to get the engine started. Its a Honda GXV (390 i believe). The way I got the engine started was by taking off the air filter and spraying alot of starter fluid in it. The engine turned over, and would run for about three seconds, presumably just burning the starter fluid as the fuel. After taking apart the gas tank, removing the filter, ensuring that the On Off fuel switch was working, and still having no luck, I drained the oil canister right beneath the air filter (at least I think that was what it was) It was draining gas from the tank, so I know that the gas On Off switch is working. So the bottom line here is, why is the engine not staying running, and running just off of the starter fluid? What do I need to do to fix this problem? Thanks in advance

PS I have not been able to check the spark plug, as I dont have a long enough wrench, could a bad spark plug cause this problem? If its not the spark plug, what is it?

Look, I know you didn't pay much for it and you have determined the engine runs, but this is a Honda and they make one of the best engines in the world so if you want a nice tool to work then you're going to have to do what it takes. So the first thing is you do need to change the spark plug, the air filter, and the oil (and filter if it has one), and since we don't run engines outside of their maintenance schedule now is a good time to bring the maintenance up to date.

Then we talk, but you ruin this engine and it's as good as throwing $500 away so first things first.

X2...do those things first. Then after that, it sounds like you may have a carb problem.

classic case of not getting fuel. once the ether burns off it dies. start with cleaning the carb really well, if that doesn't work look into rebuilding or replacing the carb and she oughta run good after that. if it's sat for awhile probably just a good cleaning will get it going

W...T....F...???? Spark plug? Air filter? OIL?

As was mentioned, ya need to go over the carb. In the end you'll prolly need to get a new carb, and a couple of mtg gaskets, and you'll be good to go.

Pay no attention to the man behind the curtain..............
