:no:

We have a 1998 Polaris Xplorer 300. Havn't had it running for about a year. It cranks, has good spark but will not satart without starting fluid. 1 shot in the carb, full choke on and it starts and runs, on very high idle for about 45 seconds then quits. Another shot of ether and it starts again and again shuts down. I can't slow down the idle using the idle screw on the carb. and when I move the chock lever to middle or off, it still shuts down. Any ideas from the xperts?

the reason it runs on high idle then quits is because it is on straight ether. You r not getting fuel intothe carb. i would start with cleaning the fuel tank and lines and carb. also rebuild the diaphram pump and check your pet cock. if that is all ok then i would say that you have a vacumm leak causing your vacumm fuel pump not to work.

Well, I took the carb apart and found nothing visibly wrong with it. Didn't check the petcock. Not to sound like a complete doofus but where is the diaphram pump located excatly?

I agree, drain the old fuel if it has been sitting for a long time. I still feel that carb needs a rebuild.

      1988 big bear 350 no spark
      By 88bigbear
      Bought a 88 big bear 350 4x4 took it for a run and lost spark, found it was stator so I replaced that then took it for a long run and it sat for 2 days and no spark again, this time stator tests good on ohms and voltage for source and pick up coils so I started replacing things including regulator, ignition, ignition coil and plug cap, spark plug and everything tests great including all safety switches until the orange wire for ignition coil from the cdi it only reads 3 volts so I replaced the cdi and still 3 volts, any ideas??

      Fixing for a friend. Atv was at a different friends house to be fixed and he rebuilt the carb and had it running nice, then it shut off and no more. He replaced the key and the coil.
       
      So he got busy, so I am helping, I checked the wiring from the stator to the cdi, and from the cdi to the coil. All is good. I checked resistance on the pickup coil, good, and on the source coil, open. I buy a new stator (China) and the 4 prong plug only has 3 wires in it while mine has all 4. I checked resistance in the source coil and it's in the 300's. I pulled one of the old pickup wires out of the old stator and wire it in the new one. Still no spark.
       
      Why do the wires differ, I checked the VIN again and it's "J" for the year and I got a 1988 stator. Please help!

      2006 Polaris Sawtooth No Spark
      By LashinWheeler
      Hello all, I have a 2006 Polaris Sawtooth with no spark. It has a dead battery but with a jump pack on it, it will still not Spark. Plug is good, Throttle ETC is not closed, Stator pick up coil seems to Ohm out in the correct range, Unsure how to properly check the CDI. And when ignition is on the Neutral and reverse light come on but after cranking just the neutral stays on. 
       
      Any help would be great,
       
      Thanks!
