Throttle stop screw.
On the left side of the vehicle, looking in at the carburetor, notice a screw pointing straight down near the bottom of the carb, slightly forward.
Turn the throttle stop screw clockwise to increase idle, counterclockwise to decrease idle. It is best to adjust the idle while at operating temperature, but be careful, it's hot in there! just bring it up until it smooths out.
Do not overcompensate to mask something more serious like a cracked or weathered intake manifold.
It is not an issue of 'If' the intake will fail, It is 'When' it will fail. Just fix it before it fails you at a less convenient time. Not good on a trip I can tell you that.

"adaptive fuel correction too rich". Could be your O2 sensor.

Polaris ATV | Answered on Jan 03, 2019

The fuel pump should not run continually when the motor is not running. I am assuming you mean when you first turn the key on, not when the motor is running as you would not hear it at all over the engine noise. (and would not run)
When you turn the key on, the fuel pump should still have retained enough pressure to only require a quick blip or two from the pump. You may just not hear it possibly.
But if it is not functioning correctly, read on.
First, the fuel pump is non-serviceable. It also includes the fuel sender and pressure regulator.
It gets better.
The fuel pump is an integral part of the fuel tank meaning you must replace the entire tank to replace a faulty fuel pump.
You can perform a fuel pressure test if it powers up, if not perform a continuity test. There is also a voltage test to check. If all the tests check out ok, but there is still a problem, take your machine to an authorized Polaris dealership for ECU testing.

Raze the track off the ground , there is a adjustment bolt on the chain case losing the check nut and turn the bolt by hand until tight, then turn the track and recheck, you might have to take the exhaust off to get at it, If i was you i would take the chain case cover off clean and every thing and put new oil in, most people don't even check the oil and then blow the chain, the oil thins out in the summer and drains out a littly each year until theres none.

Clutch. Spring rates dictate rpm engagement.

If the water was drained then filled with gas again and only ran about 20 yards, it is quite possible the residual water caused the piston to gall on the rod, meaning possible replacement or rebuild. This would be a worse case scenerio

The only thing which comes to my mind is that the KNOCK sensor feels some vibration in the engine and shuts it off?
