This is a complicated problem.. it could be in the rear differential... or the crankshaft, or the transmission... this is a job for a professional mechanic...

Check to see of water soaked the air filter(remove the filter and see how it runs!!)

Well, it was probably not the starter causing the knock. Does it knock while running? I really need more info.. please repost with more details.

First, make sure the gas tank is full!! Install a NEW spark plug. Make sure the kill switch is in the ON position. If this doesn't do it.. Time for a little more serious investigation.. Is the carburetor getting gad to it?.. there is a little screw in the bottom of the carb(flat head?).. loosen it a little (a couple turns and gas should run out),,, if it does shut the screw off.(this is good) If not, you have found the problem. Beyond this, you need a professional mechanic to help you.

When starting in gear there is a switch , controlled by the front brake lever to avoid over revving, make sure the front brake lever is fully applied when starting in gear , if the engine starts to run rough disengage the brake lever fully, if rough running continues then likely switch needs replacing/servicing

The first one you see (rotating the flywheel in the correct direction) will be the actual timing mark, The second one will be TDC (Top Dead Center) - this is the position the crankshaft must be in/on when assembling the engine/timing the camshaft.

Check your valves or valve shims

Starter locked up or starter clutch bad

That wrench means you need to service it check for spark check oil level (some have a safety deal in it) check if your getting fuel check your air cleaner

You might wanna check your shifting forks in motor

Need to adjust the throttle cable by the little nuts in line up by throttle and for idle there should be a screw on side of carb up above the over flo screw (which is on the bottom of the bowl)it will be right above the bowl start it up and turn the screw one way will make it idle up the other way idle down

Silly questions! Is this a kick or button start? Is there a security 'Dead' switch fitted to the ATV that you have left on? Have you changed the actual spark plug? Is the Battery fully charged? Turn all the other features off that you can on the ATV before you start it. This stops any other drains on the voltage at starting.

You will need to find the VIN number stamped on the bear cat's frame. You should be able to use this to source the vehicles original details when it was first registered. The VIN number is a set of 17 letters and numbers. The 10th digit is a code letter/number for a particular year after 1981. **NOTE** From 2010 the letters are re-used so registration documents would be needed if the vehicle appears older than these dates.

It's in the MAF

bad starter would be the place to start

yes it can so can anti-freeze but usually gas from carb floats sticking and leaking back into cylinder can cause hard starting and can clean oil off bearings causing damage https://www.polarisatvforums.com/threads/gas-in-oil.10700/

2000 and 2001 are likely to be the same or close enough.
