Mikuni Carbs

[udontknowme]

i have some carbs that i need to clean. someone previously left gas in for a very long time and theres a bunch of sludge and crap all over. problem is they have some plastic nipples on the outside for the vent lines. anyone know if this stuff will bother the plastic ?  http://www.walmart.com/ip/Berryman-Chem-Dip-Carburetor-and-Parts-Cleaner/17491945

Most carb cleaners aren't very food on plastics but I have used it to clean plastics for welding.
