Try contacting Troy Built, they may be able to give you a model number 
for the the engine, or at least the model number for a replacement engine.

I suspect that if you are looking for a bolt in replacement that you 
will need to stay with a Briggs engine, the mounting holes and shaft 
position may be hard to match between brands.

It sounds like you are planning on keeping the mower for as long as you 
can, so I would go for the best engine you can afford. I find that 
things powered by a Honda engine start easier, require less maintenance 
and last much longer than the B/S engines. I've had Honda engines on 
Miller welders, plate compactors, tillers and generators that outlast 
other engine brands hands down. I understand that when a Honda engine 
starts giving you problems that it is best to replace it rather than 
rebuilding it, but that is after about double the hours of other 
engines. YMMV
