Welcome to the forum. Speaking for myself, I (and probably most of us) have not added anything to your post because of my very limited knowledge (none, in fact!) of the Tr and TS series of engines. Most topics are related to, as Gary says, the older models. Please do keep posting, we welcome all Lister/Lister based systems. Even if we are not "up-to-speed" on some of the Lister models, it is a learning opportunity for us.
Thanks for posting, wish I could be of some assistance........
Cheers,
Hugh
