accel pump lever boot needed

Hello all,
Just got home from a nice vacation up in Maine(camping),and took my 74 REPU carb to rebuild while i was up there.In the process of the rebuild i noticed the rubber accordian style boot that goes around the accelerator pump rod was damaged.The rebuild kit i had didn't come with a new one.Is there a source for one?Also on a side note I didn't get into replacing the secondary diaphram because the kit didn't come with one and the one on the carb seems to work fine.I noticed after i was done(typical guy reads the directions after)that the directions said i should soak the leather acc pump diaphram in "light oil".What do they mean by light oil,and is this absolutely needed?Aside from alot of gunk in the carb i didn't notice anything out of the ordinary(then again i have never seem the inside of a carb before)unless "gross jets"are out of the ordinary.I put in new needle style jets and re set the float levels(i hope i did it right).


74 green REPU w/factory air
Early production 79 Spark yellow RX-7 GS

You did it right if you were very careful and precise, and followed those specs. ... the 'light oil' can be a number of things, but for the leather cup to seal, and last, it likely does need to be wet with something... I've used Marvel Mystery Oil before... I take it you measured 'float drop' while holding the carb upside down? Cleanliness is next to godliness... careful tightening of screws, and 100%sealing of gaskets as well... If in doubt about anything, go back and check before installing. You might want to solder up the 'vacuum bleed off' jet to increase vacuum to the secondary diaphragm...
The rubber boot is one of those 'good luck' parts... find it in a 'better' brand of carb kit (?), or run without...
