Help! Polaris 2001 325 Magnum Not Running

[PupATV]

Hey guys! I am new here to the forum and need some help getting my Polaris 325 Magnum 2001 Running.....So I got it for free and it has never run quite right...I put a aftermarket carb on it last year and it was running fine but it only went like 20 maybe 25mph max......But then the needle and seat sealed leaked within a yeah and it flooded it REALLY bad so I changed the oil because it was full of gas. So then I put a genuine Polaris carb on it and I have it set to all the factory specs, but it was still not running right....So I replaced the ignition coil and the spark plug and that solved one of the problems I had (It would bog down and stop running when i would go up a hill) But it still didn't have that much "Punch" to it like my Kawasaki Prairie 300 ans Suzuki Kingkuad 300.....So I replaced the CDI but it's still not running right! It's acting like it rich kinda....So it runs mostly okayish when I have the airfilter on but the top of the airbox off but as soon as I put the airbox lid on it like REALLY bogs down and wants to stall really bad. I have the carb at the factory specs and it has a pretty new fuel pump so I have no ideas whats going wrong! It still nly has a top speed of only about 30-35mph and it sounds like it's choking the whole time! Thank you for sticking to the end, and I hope you guys can help me!

It sounds like you have done almost everything. It does sound like it s running rich or not getting good air flow to the box, i would check that out try adjusting the carb check the needle position or even try leaning out the carb a bit. I would also be curious if the compression is in specs. Im sure as much as you have done you have probably already tried all this, thats all i can think of right now.

Yeah, I did try a compression test but I think it was 96psi which I believe is normal.....I know before if I turned off the fuel valve it would run really good once the float bowl drained down a good amour but then of course it stalled....I tried it again after replacing the ignition coil and the results were minimal...Is there any chance the (I think its called a magnito) is bad so its not getting a strong enough spark?

It is possible the pickup coil could be bad, you can check that by unplugging the stator from the wiring harness and check the resistance not sure of the values for your bike or wire colors but it will be listed in your manual.
