jeepboy_90 Postad 20 Juni , 2015 Rapport Share Postad 20 Juni , 2015 I am not getting much vacuum through the port on the carburetor. Other vacuum sources have over 20. (@ 4x4 solenoid) I have made sure the hole is not plugged in the carburetor and can feel a very light vacuum, but nothing that reads on the gauge. Really would like to get the vacuum advance working on my B30. Thank you...any tips... Citera Länk till kommentar Dela på andra webbplatser More sharing options...
Frippe S Postad 20 Juni , 2015 Rapport Share Postad 20 Juni , 2015 You have different amount of vacum depending on how you are driving, idle, full throttle, or engine brake. But IF you do the readout on the axle diff actuator as an example you get what the vacum tank has collected during time and it should not be the same.

jeepboy_90 Postad 20 Juni , 2015 Författare Rapport Share Postad 20 Juni , 2015 Thank you for the reply, and I agree with you. If I place a vacuum gauge on the ported vacuum it should increase as I apply throttle and decrease just the same when throttle is unapplied. What is the standard vacuum at 2000 rpm? The gauge reads zero throughout the testing, however like I said above I can feel a very slight pull as the rpm increase. Citera Länk till kommentar Dela på andra webbplatser More sharing options...

The vacuum is strong enough. Now you do not have the device, but when checking the carburetors and synchronization of the needle deviates by more than 1.5 atmosphere with a minus sign .If the engine is idling, the device shows about zero 1 Citera Länk till kommentar Dela på andra webbplatser More sharing options...
