Some of the noise is down to being in a small space but even so, it doesn't sound quite right.
The bigger problem is the idle.
Starts quite easily but then will rev up by itself for 5 seconds.
Then revs drop and it seems on the brink of stalling before revving up again.
Seem to oscillate back and forth for a few minutes before sort of settling.
The video is after a few mins of running (very dull video, sound only really).
