    You can mix & match air bleeds as needed.

    What is the driving cruising fuel pressure ?
    What is it pulling hard in 3rd or 4th gear top end 90-120 mph ?
    At least 80 mph ?
    If out of spec pressure drops off your beating a dead horse tuning.

    You could, but typically since we are talking about the IDLE air bleeds they would be all
    the same. Just like all 4 mixture screws are typically set the same.

    What problem are you trying to solve by setting the IAB's different?

    It was a idea to fix the problem temporarly, but I got the IFR's yesterday.
    But it was too late for me, we where out for a 650 miles trip. The 55 did it well, the driving was a bit on the rich side under 2.5oo rpm. our travel speed was 80 mph and a bit more at this range the AFR was 14.4 up to 15.1. My high speed for a few seconds was 105 when I tried to make an Audi driver angry ;)


    I can't tell. I am still waiting for my fuel pressure gauge. I only installed the typical under the hood gauge.

    I changed the IFR from .035 to .033, the tendency is the right way, still a little rich from idle to 2.000 rpm. WOT is way too rich, I got 11.4 AFR. But first I will finish the idle and cruise range, than I will tune WOT.

    Did anyone know a carb shop where I can order 10/32 air bleeds in 3/16" length? I have 1/4" length and they are too long. They work but I got a whistling sound when the engine runs. I need two sizes .069 and .068.

    I need set screws. The guy who send me the other ones answered me. He can send me the ones I need.

    I ordered a new steering box for the 55. It is more complicated to get the old one out than I thought. But it is possible without taking the front apart I think. I'm waiting for a two arm puller to get the steering arm off. After that it would be possible to get it out.
    The new steering box is a quick ratio 16:1 manual from Lares.
