Re: Stock 79 Spider 2000 carb rebuild time
I don't remember how the choke worked on my original carb (just like yourse), but on my 32 adfa I have to press the accel to the floor and slowly release. that sets the choke and the start is easy-peasy. When I first put it in i pumped and pumped, and just had a heck of a time, but it would eventually start in within 4 tries. then one day I was reading the article that Brad "R-teeg" put out, he mentioned "to the floor with slow release" and that starts my baby up even in 20 below with wind chill. Someone will chime in if that's not the way yours works, but until then, maybe it's a simple method change to get it to start easier.

all carbs with automatice chokes should be started that way when cold

Re: Stock 79 Spider 2000 carb rebuild time
for some reason I always thought my auto choke Buick Skylark had an automatic choke that would choke completely automotically. Is there a term for carb's you have to do this to, like "semi-automatic" because it's not so automatic if you have to do something to get the choke to set???

Re: Stock 79 Spider 2000 carb rebuild time
the choke can't close completely unless the throttle is partially open, nor can the idle speed screw reach the proper step on the fast idle cam until the throttle is partially opened

Re: Stock 79 Spider 2000 carb rebuild time
you are quite welcome. just kidding... but i knew those bolts were loose. glad that tightening them solved your poor/no idle situation.
the 32/36 will not come with the ball and socket style linkage. it will come with a generic style piece that is not usable for your car.
look at the connection of your existing carb....if you are REALLY adventuresome, you can create your own linkage from your old carburetor for the new carburetor....though i would recommend buying the piece you need from the supplier (less hassle).
personally, i would not recommend changing to electric pump. stay with the mechanical pump.
there used to be a check valve in line with the carb before the pump. sounds like yours has been removed, or the one that is there has failed. do you see a flying saucer shaped part in the fuel line right before the carburetor?

I think the consensus is to ditch that valve, no?Hvnfn wrote:Hey, no kiddin... thanks for the suggestion...

Re: Stock 79 Spider 2000 carb rebuild time
I cannot remember. it has been too many months since i stuck my face in front of a carburetor. check this out
http://www.piercemanifolds.com/linkage.htm
scroll down about half way..... which one of these goes with the 32/36.... i am at a loss to remember, but it is certainly one of them with the ball
I will try to find my receipt from pierce for my set up.
as far as the "UFO" valve, if you have it.....according to Chris Obert, and I know no one more knowledgeable than he, this part was recalled by Fiat due to a leak failure. Yes, leak! Leaks that lead to engine fires.
the recommended fix per the recall notice was to discard the valve and replace with a straight piece of hose.

Hey MBouse, were you able to locate a reciept?
If anyone knows what linkage is required to hook up the DFEV carb to a '79 Fiat Spider, could you please jump in and tell me? I am purchasing a DFEV from a company for a decent price, but they do not have the linkage for my car...
Thanks!

Re: Stock 79 Spider 2000 carb rebuild time
OK, several of you have mentioned also replacing the restrictive exhaust manifold... What year Spiders had the 4-2-1 configuration? Did all of the 1800's use the 4-2-1 or did some use the 4-1? My books only show the 4-1 configuration.
Thanks!
Thanks!

Re: Stock 79 Spider 2000 carb rebuild time
I did the deed and bought the DFEV today. It cost me 301 after shipping and included the base gasket and the 2.5 inch air cleaner as you recommended, Mike. Now comes the fun part of taking all of the emissions stuff off! I will follow your directions in our fine email discussions!
One thing of note, I have had a heck of a time finding all of the right size plugs for this 1800 intake... primarily the largest hole... I thought it was an M20 1.5, but it turns out to be bigger than that... perhaps 21 or 22! I am wondering if it would hurt to use an oversized oil drain plug? I am a bit nervous about cutting the threads, but I have had a time finding a plug that will fit out of the box at the local stores.
