old school ek1 cvcc carb fuel tuning

i have an 82 accord 1.8 cvcc carb motor few questions

what does the 8 ohm resistor inline with the fuel pump for? will i get more fuel or blow stuff up if i bypass it?

what needle and seat combination flows the most fuel?

is there any proper way to enlarge the jets besides drilling filing them out?

what reason does the check bb in the vacuum secondaries serve? (mines been ported and de bb'd

any larger fuel pumps that fit my low psi system 2.5 tempted to switch to mazda rx7 first gen fuel pumpp 2.5 psi but larger flow ( 8 ohm resistor?)

even though i have the oil sensor unplugged the fuel pump relay still works?
gauge in place of neat little light bulb thing in middle of dash fits really nicely
