got it right :yeah: saweet

so the more you advance the timing the less the rack moves???

no the more you advance the rack the more it retards the timing :ph:

:U:

913 pumps came in many different CPL ratings.

If his has the flat top plungers then its not the 215hp version.

so what is the point of the pump retarding timing shouldnt it advance timing through the rpm band instead of retarding it :humm:

Emissions.

could you reverse it and make it advance the timing somehow?

OR I have a 913 pump that has 911 plungers put in it

ok the things on top of the injector pump that the injector lines come out of, are those the delivery valves??

under there yes
