General Carburetor and Chrome Air Box Orientation

[stevenk9958]

I'm new to putting engines together and my 1978 Fiat 124 Spider Coupe came from the buyer in pieces. I have a new Chrome Air Box and a new Carburetor and need help with the orientation of how the box goes on the carburetor and how to mount the carburetor onto the engine.

Referring to the attached pictures can you let me know the correct picture orientation by the letter of the picture? The Chrome Air Box has a white nozzle at the bottom of the box, should it be mounted with the nozzle pointing to the right in respect to the carburetor in picture A, or pointing to the left in picture B?

Next, what is the correct orientation of the carburetor sitting in the engine bay, picture C or picture D? Both of the carb pics were taken from the driver's side bumper looking into the engine bay.

Thank you for your help.

Until any more 124 Spider owners come forward , I have this from an old DIY manual which appears to show as in photo D , your last pic. Note these are Solex carbs not Weber so may differ . Pic appears to be for a LHD drive vehicle so could be relevant.
Also the throttle linkage on cam cover appears to line up with carb in that photo and auto choke mechanism facing rearwards.
Obviously check what other say and what looks most logical.

When I converted to a 32/36 here's how I set my 79 up if this helps any...

Do you have a tube coming out of the bottom of your chrome air box? If so, is the box mounted so that tube is closest to the round faded yellow plastic piece with the wiring attached to it? That would mean that I mount the box to the carb as in my picture B correct? My version of that yellow piece is black, but looks like the same piece.

Hi Steven..yes it appears like your picture "b" , the part on mine that is white with the wire attached, and black on yours is your electric choke , the hose attaches to the tube coming out the bottom of the air cleaner right next to it...if you enlarge the other 2 pics I posted you can see it but here is a little better picture! Hope this helps!

P.s. , your picture "D" is the correct carburator orientation, it can only go on one way in regards to your throttle linkage..

One more thought...I know it can be tough putting something back together that someone else took apart and you didn't get to see the process , but before you put everything back together, did the previous owner share with you "why" they were disassembling things? In other words is there a issue that needs to be addressed "before"you reassemble things so it doesn't simply reappear and everything needs to come apart again?

Hi Terry,

Here's what my seller said: "I wanted to get the timing cover off, change the belts, and re-do the timing".

Well that doesn't sound bad I guess...leaves you the options of reassembling it and getting it running to assess its condition for yourself, or proceeding with their planned maintenance..
