I need serious help with taking out the carbs on my PWC.. It appears that I need to take out the one section of the exhaust, but for some reason I can not take it out. I pulled all the bolts holding it together, however there are these two pins that hold a seal together.. At least that is what the diagram in the manual shows.. However, I dont know how to take it off. The problem I have is that it needs to come off, because the two carbs are underneath it.. I want to rebuild them, because this season did some damage to one of them.. I think its an ethenol issue that killed my diaphrams.. Any assistance would be awesome.. I could even provide other contact information for a more detailed conversation on it. Thanks!
