I need a new carb for my 73 cougar Xr7 with a 2bbl automatic trans, auto choke. I found a reman guy who has one listed for a 72, but his ad says it is my responsibility to verify that it is correct. Are they interchangeable?

Thanks
Gary

 

Do you absolutely want a 2bbl? Unless you're trying to stay correct, its a pretty small carb for that big of an engine.

 

yes, i am basically looking to replace the carb with what was on there originally, don't want to change aircleaner, intake etc.

 

Get the model numbers of the carbs and post them.

 

According to autozone the 72 and 73 carbs have different part numbers, they look the same but it looks like the 73 has an extra metered vacuum port . They possibly may have different throttle linkages. I would pull yours and take it to compare to the one the guy has. Both carbs are 2100d series and likely the same cfm.

If you ever want to wake that engine up you can get a 4bbl intake from the junk yard for about 50 bucks and drop on a nice edlebrock or holly 4bbl.

 

Rebuild your original, either do it yourself or send it to a shop to get it done. Sounds like you're looking for originality.

 

+1 on rebuilding the kits are about 20$ on www.rockauto.com its pretty straightforward if you just take your time

 

The 73 carb is different due to new government emission standards

I would recommend this if you don't want to rebuild your old carb -
