I am rebuilding and rejeting the carbs on my 99 xlt 1200 to get rid of the acell pump and discovered that the acell. pump nozzles on all three carbs are blocked. You cannot blow any air though them. It appears that the tip of the injectors dont have a hole in them!!!! I could never figure out why ski was hard to start and would stumble and die if you let ski sit for any length of time. If you got ski fully warmed up it would run pefect. Anyone ese run into this problem? The only reason i found the problem was because i was going to use the injectors for a primer kit and was blowing through them to make sure they were clear.
