I have a 98 Polaris Magnum 425. Runs GREAT for 10 minutes then starts to load up (sounds rich) and looses power. Final;ly just stalls out on idle. If it sits 20 minutes will run again.
replaced fuel, added fuel treatment (seafoam), Replaced plug (carbon fouled), plug wires, air and fuel filter, checked all fuel and vac hoses, REPLACED carb with new. Still no good. Just ordered a coil, not sure if that will help
Note: both the new and old carb only had the idel adjuster screw - cant find the jet adjustments or air/fuel mix screws so I cannot say how they are set.
Looking for ideas short of spending big $$ on Polaris service
