FI plenum rebuild parts

Post by BammBamm »

I am building a motor for my 82 Spider. The intake needed a complete overhaul. I order the normal gaskets but when i look at it in detail there are a few parts not listed in the exploded diagrams. They look like some orings. There are in the intake for the throttle linkage and one on the shaft itself. Then there is another oring on this bolt (i dont see this bolt in the diagrams either). I also need the the cold start oring. Where can i get these?

That looks to me like an idle speed screw.

Lists every part number for everything in the FI system. You may be looking for parts that were not sold as individual units; i.e. the throttle body parts were generally sold along with the entire plenum top. However, some help:

The idle speed screw O-ring is 10mm OD and 6.5 ID. I can buy them at Ace Hardware near my house, they are in a big O-ring rack and won't deteriorate when exposed to fuel/ethanol.

Is the top picture of your throttle body with the accelerator removed? I can't tell which side that is, the TPS side? Look at the microfilm page 46, it shows the entire throttle linkage with all P/Ns.

great. I now have the idle screw oring size. Do you know the oring size for the cold start valve 4421169? or the oring size for part 4446157?

Nope. You can order it though, and measure it, and tell us what it is: http://www.autoricambi.us/product/FI0-0 ... -Injector/. Some of these FI parts are a bit odd - CSI o-ring is a fat little thing.

I don't know the other either, sorry.

Just curious if anyone was able to find out the size of the cold start injector o-ring?
