I looked into this a few weeks ago, after doing this job succesfully on my
1974 Volvo 142, but I couldn't see how I should compress the valve springs
on the MGB engine. The point is that the valve springs on an MGB are double,
so what do you do? I have a Deslisle valve spring compressor which hooks
onto the valve springs and then pushes down onto the valve cup so you can
remove the keeper circlip and the keepers. Getting the spring compressors
hooks in deep enough so they can reach the inner valve spring seems
impossible. Any tips, John? Anybody on the list ever done this?

Dirk, with a '66 B which smokes on start-up.
