6-Pak Diaphragm Spring Kit

[cwestra]

Summit sells several diaphragm spring kits, but none that specifically call out the 2300 series Holley carbs on the 6-Pak set-up.  Does anyone know if any of these kits will work for the 2300's?  And if so, would I need to complete kits?  All I am looking for are the lighter yellow springs.

Also, who sells the clear sight bowl plugs?

The six pack carbs use the same diaphragms and springs as the regular Holley 4 barrel carbs. And yes, you have to buy two kits.

Not true.

Same springs, different diaphragms. "Yellow" is the stock spring.

Sight bowl plugs can be had through Summit (and other sources) as well. I recommend using these while setting the float level, then swapping back to the regular plugs. The clear plastic plugs get brittle over time and have been known to leak.

Thanks.  My springs are old and not painted.  Is there a way to determine which spring it is (number of coils, diameter of wire, etc...)?

Not really. If you had a set to compare with, you might. The wire gage and coil count varies, so it's hard to tell the difference.

I bought holley spring kits # 20-13 for mine.  The instructions say the plain spring is the standard spring.  I just swapped in the short yellows to open the outboards earlier.

Thanks.  I guess I'll order a couple of those kits.
