I've now located a shop that can mix the fuel that I'll need for a plain bearing engine, so I've placed an order and now we'll see what the local post could possibly do to stop this (I keep my fingers crossed).
I will use this in an MVVS 1.5cc RC and possibly the TT 07 then...

If the conversion is succesful will Davis then be able to manufacture a few more do you think?
I could possibly machine a head myself, did that to take the turbo plug, but I haven't done any diesel ones before and these do have a lot more parts in them...
