215 AMF units is indeed rather small, and (as you can see in e.g. 
txtfdmns.etx) the stretch and shrink of the space is by default 
propotional to the space width, so you may indeed want to override 
this. If the spaces are too small, the text might become hard to read 
because words get too close (OTOH if the spaces are too large it also 
gets hard to read; it's one of those fuzzy issues that have to be 
judged from proofs).

Setting the interword integer will scale up all the space-related 
metrics, so you could try including
   \metrics\setint{interword}{250}
as an extra item in the \installfont metrics list.

If instead you just want to allow for more stretch, you can do e.g.
   \metrics\setint{stretchword}{150}
instead. Either should reduce the amount of overfull boxes.
