spuutering air

[dub88acc]

I have a small problem but i guess it hasn't done much harm to the weber since i'm stiull using my car. But my weber 32/36 keeps sputtering air everytime i turn the car off. Sometimes it doesn't do it yet sometimes it does. I thing one of the vacuum plugs is cracked yet i don't know what the real problem is. any help?

replace the rubber plugs.
they are cheap.
if that doesn't fix, check your timing.
