Tunnel ram or no tunnel ram...

In case of IFR my understanding is that these restrictors deliver only gas so they can be rather small. In my case t-slot restrictor was not allowing the engine to pull right amount of gas in the transition slot which resulted in very lean condition.

I get that. I guess what I’m asking is do the transfer slots get their fuel directly from the main well? And in my case whenever I’ve gone down in IFR, my transition has leaned out a bit also. Is that simply from there being less fuel in the idle circuit? Or is there a direct relationship between the IFR and transition? It’s my understanding that the engine pulls from both the idle and transition until the mains come in.

Edit: Found info I was looking for on an old “SpeedTalk” page. IFR/IAB supplies fuel for both.
