spookefoote,
I'm driving on the right side, it's you that's going the wrong way.
Pretty sure there's nothing loose causing it, checked everything when I reassembled after taking the head off last year to fix pushrod tube leaks.
I've listened to the video several times, used the stethoscope and me ears. I dunno, it could easily be valve springs as Clive suggested. Thing is, she starts and runs really well and seems to have plenty of power (sic), so I'm reluctant to mess with it.
Maybe it's just general wear. I think engine is all original, certainly the cylinder is std bore as I measured it when the head was off. Only recently set rocker clearances, on the loose side admittedly though rattle was there to a degree previously.
Think I'll monitor it as with the oil use and see how it goes. Hopefully not ‘Bang'.
Thanks all for the comments, I'll be back if something changes.
Steve
