Can't figure this Polaris problem. (1992 650 carburated with Decker pipes
and kit - only 1300 mi.) Engine groggy when first started this year. Found
mag exhaust ice cold. Plug seemed to be firing. (cleaned carbs changed gas)
Thought coil or mag side seal problem. Bought new plugs and placed mag side
coil to center spot and visa-versa. To my surprise centre and mag side pipes
were hot while clutch side was ice cold. tried many variations on plugs and
coil placements but will have one outboard cylinder cold at any given time. Raw fuel/oil will pass through this pipe. Do I have an electrical problem or are
the case seal/seals shot ?????
Any help or thoughts would be appreceated.
Thanks,
Ron D.

If raw fuel is passing into the pipe it sounds like it didnt fire. You changed all the combinations of plugs and coils but did you try isolating which plug wire. mark the wire and move it from cylinder to cylinder to see if it could be a wire or cap problem.

as usual, owner stupidity! When removing/cleaning the carbs I accidentally
changed the adjustment on the chokes. Readjusted and have a fine running
Polaris again ! Thanks for helping !

Great news Rondv. You tricked me when you said the problem moved from outside to inside cylinders You must have swaped the Carbs or choke cables too ......I guess?
