I have obtained a 9 mm head and a 1.9D pump for spares.
I hesitate doing gov mod. 1.9D has stiffer gov springs: both intermediate and the long one that is shimmed. Specifications say it has 5100 max rpm vs 4800 rpm of 1.9TD. Maybe I could use the gov from 1.9D as an upgrade instead of shimming 1.9TD gov? Please advise. Is there anything else I should take from the 1.9D pump?
Thanks!
