My father has a 2004 Polaris TM Ranger with the Robbins engine.

Question is, we wonder if anyone has had problems like we have had with the carb not shutting off the fuel and filling up the crank?  We have taken the carb apart and found that the soleniod plunger that shuts off the fuel to the main jet keeps denting the main jet which allows fuel to seep by and over fill the carb which then leaks into the base.  We changed out the main jet and it worked fine for about 10hrs but now its doing it again.  Its a pain in the butt to keep replacing the main jet every 10 hrs or so, does anyone else ever hear of this and have a fix??

Thanks in advance!
