Strimmer Carburettor Rebuild - fixed in under an hour and for less than £10

Published at : 13 Dec 2025

In this video, I bring my strimmer back to life, by cleaning the carburettor and replacing the fuel metering diaphragm, since I noticed it had a small split. After a quick tune, this seems to have brought it back to life.

Make/model:
Flymo Maxi Trim 430
