I got my 914/6 back up and running with the 2.4S conversion parts, including the MFI!! God, I LOVE the sound of MFI at full song! With the S cams it has the same scream a 917 has.


Friday morning I was running the car, tweaking some little things when the injection pump died. (IMG:style_emoticons/default/mad.gif) I only have one S pump, so I was forced to remove the MFI from my six. It will take 6 to 8 weeks to get the pump rebuilt, and I have to have a way to get to my new job on Monday. So, under duress, I installed my set of 40IDA3C Webers. (IMG:style_emoticons/default/barf.gif) I rejetted them to the settings mentioned on the Early S registry for a 73 2.4S motor.

Main Jets #32
Venturis #135
Air Correction Jets #180
Idle Jets #60
Emulsion Tubes F3

Now I have to deal with all the carb crap.... like clogged idle jets, out of sync air bleed screws, UGH!!!


Has anyone found a way to keep the idle jets from plugging up? I have been working on the car off and on since Friday, and have cleaned the idle jets 5 times.

I still have to lower the accelerator pump stroke to lessen the black smoke under initial throttle opening.

The car runs ok, but it doesn't run like the MFI does..... (IMG:style_emoticons/default/sad.gif)
