I picked up this ATV that had no spark. The previous owner said he was driving it and it died and would not start. He discovered it had no spark. He replaced the CDI and the coil with no luck. He got tired of it and I bought it. I replaced the stater and now it has strong spark. Now, it starts for a second or two then dies. It will not stay running. I have checked the timing and it is spot on. The valves are adjusted correctly. I see no warn issues with the cam. I put the original CDI and coil back on it. Same problem exists. Compression is at 65 psi (has decompression mechanism),
I took off the muffler in case the issue was clogged pipes. No change. I replaced the spark plug. No change. The carb was an aftermarket so I put a Niche carb on with no change. I bypassed the fuel pump and that did nothing to solve the problem.
I don't know if this is a carb issue or an ignition issue. I am looking around locally for an OEM carb to try out but not sure that will fix the problem.
Can anyone help me solve this problem. I am running out of ideas.
Thank you for your time

While wiring in a set of reverse lights I discovered the diagram is wrong concerning the shift position switch. It is shown as LHNRP but its backwards, PRNHL
L/W and R/Y wires close on reverse, not L/W and GR/G. Found out the hard way and had to re-do it.
Diagram is Alterra 600 LTD

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!

I have acquired a free 92 Polaris 350L 4X4. Ive replaced carburetor from ebay, replaced spark plug, im trying to pull start but sounds like it doesnt want to fire. Spark is a bright orange spark (checked with spark plug tester), replaced plug, pre mixed gas from an external gravity feed tank. Compression test good. Anyone got any recommendations for me?
