Fed vs Ca Carb Worries

[mattcobb]

I have a 74 Fj40 (12/74) that needs a new carb. I see that there is a Fed carb and a California carb -- I do not need to pass smog or anything - Is there a difference in the two (ERG - whatever that might be)? SOR did not know the answer. They have CA in stock.

The tag on my hood has been painted over indicating ca / fed. There is no tag on top of my carb that I can see. The vehicle ID tag inside the door does not indicate fed / ca.

If I bolt a Ca carb on a Fed FJ (in case mine is a Fed) does it cause problems?

What carb - if you had to put a new one on -- would you use?

Thanks

Matt the most visible difference between the CA and Fed 74 is that the CA is gonna have an EGR tube between the fuel bowl and throttle body, just like the 75-78 US carbs. The fed spec 74 does not have the EGR tube.

They are both good carbs. I would just rebuild the one you have. A couple of good rebuilders also hang out on the board. [place smilie here]

What is an EGR tube? What does it do?

I've got a pair of 12/'74 Cruisers. Both CA spec. Carb #60280. Good carb for rebuilding.
The EGR inlet is in the second insulator up. Bottom insulator is the PCV inlet. Most of my EGR stuff went away when I got headers. You can use your carb without the EGR spacer but it throws off alignments all over. I just cut off the external part of the EGR tube from the spacer, filled the hole with JB weld.
There may be a difference in height between CA & Fed carbs due to the EGR inlet, the fuel lines may need adjusting, maybe throttle linkage too.

How can I tell if my current carb is CA or Fed

If your carb is the Cal model it will have the EGR tube. If you go to SOR.com and search under "carbs" the page with photos of the fed and cal carb for 74 will come up.
