Thanks Guys for all the good wishes.

Re the boroscope - I got a WiFi enabled one suitable for iOS:

It does come with a little 90 degree mirror but I found there was too much light scatter so got a cheapo dentist mirror and taped it to that.

Also, it took me a while to realise that the compensator was in front of the hole in the bell housing, not behind so I'd spend quite a while looking the wrong way doh

Unfortunately I can't get the video off the iPhone to post but will keep trying.

Re the rubber smell - it was pretty much instant if I put my foot down above about 4,000 rpm.
