Whistling Carb
Any idea why my carb whistles at half acceleration? I checked all the vaccum stuff and narrowed it down to the intake. Why is it doing this?
Thanx, Tracii
BTW its a motorcraft 2bbl on a 1970 390

Whistling Carb
If if is any consolation, my 1970 360 engine does the same thing. Whistles like some sort of vacum leak under accelaration. I have an aftermarket carb and thought that might be the cause? If you get a good solid answer, plese let me know.

Whistling Carb
[updated:LAST EDITED ON 27-Apr-02 AT 02:10 PM (EST)]If it IS the Carb,I would suggest the whistle is caused by a leaky Carb butterfly rod.I doubt it is the choke butterfly's.
Spary some carb cleaner around the area where the rods swivel on the outside of the carb to see if the whistling stops.
Solex carbs on Volvos are notorious for this problem.
An intake leak itself can whistle as well as where the
Vacuum tree mounts to the back of the intake.
If so,wrap some teflon tape around the threads of the Vacuum tree and screw it back in.
