Hey everybody! I just picked up a 2009 trx90 for my son's upgrade. This trx sat for 2 years and I'm preparing a thorough cleaning of the carb and fuel lines. I am considering a new one vs a cleaning, I'm worried, as I'm new to tinkering with carbs, I'm not afraid to mess up or lose pieces, I want a back up plan and have a carb in mind before I jump in. Rockymountainatv has 1 part number that replaces 2 different part numbers. Any thoughts? Any pointers for me before I jump in to a disassembly and cleaning?
