: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.

      1989 Moto 4 YFM350ERW intermittent spark.

      1989 Moto 4 YFM350ERW intermittent spark.
      Quad has set for about 7 years and was running when parked.  When I replaced the battery and attempted to start it had no spark. 
       
      What I have done.  Followed troubleshooting in the manual. 
      1.       Coil failed the resistance check so I replaced it.  Still no spark.
      2.       I performed resistance checks on the stator and they all pass.
      3.       Found a bad rear brake stop switch and unplugged it and connected the wires in order to disable.  Now I have intermittent spark.  I believe that the issue is with either the stator or CDI and not sure which.
      1989 seems to be a transition year for electrical.  I can get new aftermarket CDI units for 87-88 and 90-94.  I cannot get ones for a 89.  I can get new stators for 87-89 and 90-95.  Looking at the schematics the wiring on my moto is closer to the 90 ones on the ATV side of the CDI and closer to the 87-88 on the stator side of the CDI.  Looking at part supply sources the stator housing is the same part # for all the years and looking at some of the stators on Amazon that have the dimensions on them both of the stators are the same size.
      What I am thinking of doing is to replace the stator and CDI with a 90-95 one as these parts are all readily available.   Does anyone know if this has been tried before and if there are any issues with doing this.  
       As a side note I also have a 1993 Moto 4 YFM350ER that has been sitting longer but it is located about 400 miles from me at this time.  By doing this change in addition to being able to get parts I will also have 2 ATV’s that are the same electrically.
