First question, what do the numbers on the floats mean? I have 2 sets of lectrons that were purchased new and none of the float numbers match across the 4 carbs. I've got a mix of #s from 30 to 77. I assume they are float weights but don't know what should be in there for alky/nitro?

Second question, the carbs can be used with one or two floats per bowl. Why would you run one vs. two or two vs. one? I have Packard's billet bowls on both sets if that makes any difference.

Third question, the floats can be installed with the pin closer to the needle/seat or at the other end the float tab. Why would you run the float(s) with the pin closest to the needle/seat or at the end of the float tab?

Thanks!

do you think they might be mold #s on the floats????? idk just an idea??

I ordered new floats from packard for my 44 lectron. He told me any of the floats would work for alki/nitro mix. Not sure about the numbers.

Remove a float for more volume...bowl will hold more fuel.
Pin away from the needle and seat is for fuel pump, towards the needle and seat is for gravity fed.
(Obviously, you must have the correct type of needle in seat, pump vs. gravity)

See what Packard says regarding alky/nitro floats...

Packard said the numbers don't matter except for left/right (odd/even?). He said that they probably meant weight but he never saw any difference between the numbers.

For nitro, he uses screw in pins instead of glued in pins. That's why I started this investigation, one of my glued in pins came loose and I went through all my floats.

He said to only run one float unless you were having trouble sealing the needle/seat, then run two. I'm sure a pump puts more pressure on the needle/seat than gravity feed so that's probably one reason to run dual floats.

He said that he used to run the pins close to the needle/seat but stopped doing it and only runs them with the pins at the far edge of the float tab.

I ordered four new nitro floats and will keep the others as spares.

good info!! just shows that if you have a question ask the REAL experts sometimes you might be suprised. i always run one float on a gravity feed.. with out billet bowls i have never sucked the bowls dry even full rev in 5th gear on a 500-600ft run.. ( but thats just me)
