step, according to my manual,v-135 thru v-175 ser#c221500 & up,
flow specs
2.0 @1500RPM w/ oil pump link arm CONNECTED = 6.8 cc + or- 10% in three minutes
@1500RPM w/ oil pump arm DISCONNECTED = 17cc + or - 10 % in three minutes
2.4 @ 1500 RPM w/0il pump arm CONNECTED = 8.2cc + or - 10% in three minutes
@ 1500RPM w/oil pump DISCONNECTED = 19.2cc + or - 10% in three minutes
you check it by running the engine on PREMIX and disconnecting the clear tube going to the fuel line tee from the oil pump. block off the oil inlet in that tee and dump the oil in a measuring cup. kinda a pia, but you might be over oiling.
out of the 5 or 6 I have ever checked, i've never found one out of specs.
but you never know, if you want to try it, pm me your e mail and i'll try to scan the page and send to you.
