i was going thru some of my old spares and noticed that i have a pair of dell idle tubes 7850.4s that are different? they both should be out of RB DHLA48 12a setups? if you look at it. one has only one hole on top and the other has two going straight thru.... anyone have a clue?

thanks in advance

 

i have some details..in one of my threads:

https://www.rx7club.com/1st-generation-specific-1979-1985-18/dellorto-48-dhla-swap-13b-12a-not-56k-friendly-773154/

so i was doing my swap from using one that was for a 13b and i rejetted it for the 12a..i got idle jet holders from Dellorto..and the ones they sent me had 4 tiny holes on one and the other only had one big hole...i also had to modify them to work..by making a bleed off hole..because the ones that they sent me didnt have one..and it ran so rich..

 

this is the view from the top. would both of these be true RB idle tubes then? the tag #5010 was on the one with the one hole nearest the jet.

 

Yes they look like it. Another way to know if they are even true dellorto jets is if they have a diamond on they. Let me know if you have any ?'s

 

i'm pulling my S5 13bt streetport motor out of my FC and putting it in my Rx-3. but, going N/A with it with my Dellorto DHLA 48. Would you know a good ball park jet settings?

thanks in advance!
