Why you should replace butterfly (throttle shaft) seals.

Replaced both with the throttle shaft seals and v seals on fuel rails with a complete rebuild minus the main 120 jets. Now when I try and start it only starts up when promised then shuts down. I adjusted the idle adjustment screws out a 1\2 turn in between the starts. Next,is remove the carbs and install the new intake manifolds I just got, unless anyone has a better idea with less hassle. Got the bar clamps and heat gun ready. Appreciate any advise received on this very long and tedious task.

 

Did you wet set the floats and bench sync the carburettors before you tried to start it? You could check it for vacuum leaks too. Watch the bolts holding the intake boots to the head they can shear. Probably the original factory ones been there a long time.

 

Where did you get your intake boots? The Chinese ones on ebay are poor quality.

 

They are I just them.

 

I did the bench test and adjusted the floats to spec also I can drain each float bowl on the carbs.. Completed the "church of clean" including replacing most of the butterfly
shaft screws.. Thanks for the replies.
