will it run with the choke on .if u take the carb off try to use compressed air to blow air through the carb a little through the fuel inlet . or u could take the jetts out . they are easy to take out with a small flat top screw driver . the jets are brass so be carefull. use a lamp & look through the holes in the jets .also try to blow through them .check the operation of the the float ,needle & seat . The problem u have could also have nothing to do with the thing running out of gas . is there a throttle safety switch on the bike . is it operating . water in the fuel is the only other thing i could think of right now

So you think my quad is getting to much oil...well I did change my oil not to long ago...so whats the deal..just drain some oil out??? I can't work on it untill this weekend..but I'll try the oil first then I'll mess with the jets and make sure they are clean...but ya it idles fine..with choke...without choke it will idle for about 5 minutes then die....but its just when I give it some gas..it wants to die..I can't give it any gas at all.

When idling the fuel is sucked out of the bowl theu the idle jet. When you give it gas the air is still sucked in but the idle jet wont let enough fuel into the stream. The main jet is prolly clogged.
I'm not familiar with polaris but if it has an auto oil inject it would probably spray too much oil since there isnt the right amount of gas mixing.

This is not a two-stroke machine. Don't worry about the oil.
Remove the air cleaner, start it up, then put your hand over the intake. try to block the air and still give it gas little by little. This will cause an excess of fuel to rush through the carb and flush any small debris from the circuits.
It does sound a little like cam issues if this doesn't help.

From my experience, the comment "it was running fine... then the next time I started it up it would do nothing more than idle" usually ends up being camshaft failure on the polaris 4 strokes. Even though it was run out of gas, Quadracer18 says he has gotten it to run at an idle - changed the plug, cleaned the air filter, and drained the carb - later on he says it will run for 5 minutes or more at an idle. The fuel pump is more than primed by now, and we all hope that it is something simple such as trash in the fuel circuits, but at the same time he could spend a lot of unnecessary time trying to resolve a carb issue that doesn't exist. By all means clean the carb out and if it does not work after that, then Quadracer18 has a second option to approach.

its not the cam and i doubt it is dirt in the carb when they run out or gas it takes a very long time to get the fuel pump primed.

Maybe someone can tell you a better way to prime the fuel system, but I would lay money on this as the problem!
