Ferrari Mailing List: Removal of 308 carbureted airbox

[Robert W. Garven Jr. (rgarven]

Having done this at least 50 times neither solution works. When I tried to glue 
them on this did not work for me, because the rubber gasket moves around a bit 
and there’s also a bit of slop in between the studs in the carburetor and the 
little top hat washers For them to move around a bit so that they can fit 
together with loose tolerances. And if you put them on the top of the rubber 
gaskets, that’s not how that the design works as there is a small indented 
groove into the bottom  of  carburetor trumpets where the thinner part of the 
top hat was designed to fit. The wider part of the design rides on the top of 
the carburetor and fits into a groove that’s molded into the bottom of the 
rubber gasket also. Of course you can do both of these modifications which I 
tried among others but neither one works satisfactory, fits well or how it was 
designed to work.

As you can imagine I’ve tried all these and and Peter and I have discussed this 
on numerous occasions over the years. What I found that works really good is to 
first remove the breather hose that attaches to the bottom of the airbox which 
allows it to rise up vertically, then as I lift it up (the air box) I take a 
long bamboo skewer and just kind of push down each top hat washer till it falls 
out of the rubber gasket and sits on the carburetor top  and then you can lift 
the airbox off straight up without losing any of the washers . To me what’s 
harder is removing the 16 washers and small nuts that go on top of the trumpets 
and hold them to the airbox. I have to use two specific tools to do that 
because it’s hard to get to. Ferrari actually left some cut outs in the 
trumpets to get a tool down in there but I’ve tried every combination of 
sockets and what I used is a small socket screwdriver to remove it after I use 
a short quarter inch socket extension and short socket to loosen it first.

I have lots of pictures if you guys are that interested, but I doubt that you 
are.😎 i’m sure some people can knock this out in a few minutes but it takes me 
a couple hours to do it safely I said every moisture and not in a little lime 
to make sure that I have all 16 before I proceed.
