Fuel coming out of bottom of carb - Polaris ATV

fuel filter is in the petcock where you turn the gas on and off

There isn't one. You have to put one in-
line

Hey Scott, you might have more issues than just an idle speed, have you installed a new spark plug lately?.. had the carb cleaned and set by a qualified professional... have your cleaned or replaced the air filter?
Try these steps first.. then reply to me.

If you have the fuel petcock (valve assembly attached to bottom of fuel tank) to either 'on' or 'reserve' and no gas is flowing through the fuel line - the most likely culprit is either a) petcock itself is clogged or the filter inside the tank that is attached to petcock is clogged or b.) you could possibly have a malfunctioning fuel cap. The fuel caps are usually vented to allow excess pressure to vent off. If for any reason that fails - then basically it becomes a vacuum issue. You could try loosening the fuel cap - not completely removing - just loosen and see if the flow starts - if so, it's your cap. (Some you could shake to test function - you would hear a rattle if the mechanism was still good - not all though). If loosening cap doesn't help and you're sure you're in correct position - you'll have to remove that assembly. Two screws or bolts usually hold petcock to fuel tank. Remove those two bolts, usually a rubber o-ring type gasket or another type of gasket - and a tube/filter is attached to petcock. As you remove you'll see exactly what I'm talking about- that's actually your fuel filter/reason there is usually not an external fuel filter. IF it's not clogged - the issue lies within the petcock itself. Some are able to be disassembled, cleaned and reassembled - if not/replacing would be only option. These tips are assuming that you've removed fuel line from carb - if not, please check with fuel line removed - if you're still hooked to carb, but are sure there is no fuel flow - and fuel does flow when unhooked/clogged port to carb or your float is not functioning properly allowing fuel to enter carb. All The Best & Good Luck

Could be one of the carb floats is stuck or the rollover caused it to come off its mounting position. As fuel enters the carb, the float rises with the fuel level until it reaches a position that shuts off any more fuel entering the float chamber and prevents an overflow. Fuel level drops, float drops and fuel flows again. Basically like the cistern in a toilet.

Take fuel cap off to make sure it is getting air to fuel tank. Check fuel valve to make sure it is on. Drain carb with screw on bottom of carb to check for water. Pull spark plug to make sure it is firing.

replace fuel filter. check spark plug. fuel has waste in it bad fuel maybe.. has it been setting a long time. remove sediment bowl from carb. should at least drain the carb and catch the fuel from the drain. examine fuel caught for bubbles in bottom of fuel container. air filter clean? adj timing ? does it smoke when running? backfire? choke off ?

#1 sounds like a fuel delivery system issue. Make sure the fuel tank flows freely to the carb. (remove the fuel line from the carb--from the gas tank and turn on the petcock--gas should flow freely) The needle and seat may need to be cleaned or replaced, this controls the flow of gas into the float bowl of the carb.(remove the drain screw from the bottom of the carb (with everything properly assembled- petcock on)..gas should continually flow through the bottom of the carb --10-15 seconds of continual gas flow will make sure its flowing properly! Both of these sound like a solution to your problem.

Sounds like it has sat for a while and your jets are gummed in the carb there is a you tube video on this topic that will walk you through the repair other thing to check turn fuel tank valve to off position remove fuel hose at carb slowly turn valve on to see if you have fuel to the carb if there is fuel there turn valve off install hose back on carb remove remove hose at tank valve now on the bottom of the carb you will see a plug or screw loosen this ( there may be fuel running out of drain hose have a bucket to catch fuel) now on the hose at tank valve blow threw it ( do not use air compressor) air should blow freely if it dose not your needle valve is stuck and there is no fuel getting to the carb or stuck float or a hole in the float and full of fuel

if its on the very bottom, no where. its a drain line for the carb bowl.
