intake Hissing?
My intake on a 360 2v makes a sucking noise coming outta
the carb area( vacuum leak) I replaced vacuum hoses,torqued the
intake down, I'm replacing carb gaskets tommorow. If
that doesn't work can the carb it's self leak? the thing revs
like a SOB, hits 5500rpm as fast as my moms toyota 1.6L 4 banger. It has a rough time idling when could, but once warm
it has this layed back lope.

Dory,
It could be the carb itself. I stumbled across a used Edelbrock 600 this past summer and decided to plop it on my 360 (for some reason I thought the electric choke would be handy). The carb whistled. Loud. I was checking belts, looking for a vacum leak, etc. Finally yanked the carb and reinstalled my old E'brock 500. Whistling went away. Just one of those n=1 experiences that might help.

Maybe that your throttle shaft bushings are worn on your carb. Take a can of either or starting fluid and spray around all the intake and carb areas . If you have a leak somewhere your engine should rev up as the starting fluid is sucked into the engine. Just my 2 $ Good luck.

I had this same problem with my 600 and I know this sounds dumb, but are your vacum plugs screwed in all the way? I know I had this on my truck and there was a plug in the back I didn't see and didn't even know was there and i put a plug in and it went away
