Zenoah K149181161 Needle Spring for G200PU-EI Carburettor  [K149181161]

Spare Needle Spring for G200PU-EI Carbs

This Zenoah K149181161 needle spring is made as a direct replacement option for G200PU-EI carburettors, restoring the spring pressure that helps the needle seat correctly and smooth idle behaviour.

Installation is suitable for hobbyists comfortable with small engine work: remove the carburettor from the model, expose the needle assembly, swap the old spring for the K149181161 unit while maintaining the needle orientation, then reassemble and bench-test throttle action before refitting to the engine. Make small needle adjustments on a secure test stand to confirm running.

As a simple replacement, this spring affects needle seating force and therefore influences fuel metering at idle and mid-throttle. Replace when tension has noticeably reduced and pair the change with routine cleaning and needle rechecking for reliable results.
