He really is a naughty boy.
I suspected a cam follower but had no idea about the other issues.
A tdi will be just the ticket for him though.
It might be worth putting 11" brakes on the front.
Good luck with the resto, Brian will enjoy having an owner with the time and skills to invest in him, he's a plucky little chap.
I look forward to seeing him at events in the near future.
