Engine noises

[Andy Bennett]

I have to say I've listened to the video 3 times now, and fail to 'hear' any problem.

Its a bit tappety, which is pretty standard for a cold 7 engine. If as you say the tops of the adjusters are a little worn, then with them set at 6 and 7 you will have a smidge more no matter what you do.

The engine I've thrown in my daughters saloon temporarily is exactly like that, a little tappety, which improves as it warms up. Pulls like a train though.

I thought the same at first but under the light tappety noise is a deeper clinking. You might need speakers rather than just laptop to hear but there is something below the frequency of tappets rattling gently to itself.
