Rotax Max Needle Jet Clip. This needle clip adjusts the fuel metering height of the needle jet (K 57) on the Rotax Max carburetor!
A vital albeit humble component, this circlip is just the right size to fit into the slots on the carburetor needle, and moves up and down depending on the mixture desired as the throttle is partial to wide-open.
Each circlip is sold separately. Easy to lose and small, this is a great item to keep as a spare for your Rotax!
