Need a second opion on the year of these carbs

[condiakos]

This is my first build. It is a 76xs 650 but after I ordered my carb rebuild kits I started the carb cleaning and believe these carbs are 78's I have read all the guides & printed them out for reference. just looking for conformation. I just finished a pma swap and a pamco and this is the only thing keeping me from riding. Thanks guys

Yeah the bodies sure look like 78-79

Better check each jet carefully to make sure everything matches the bodies. Those darned POs do the goofiest things.

I think I will just order a 78 rebuild kit

The late 78-79 carbs the needl is held in by a clip that needs long nonse snap ring pliers to get out.
The earlier carbs used a large thick plastic washer and the return spring.
The needle is a 502 and the needle jet is a Z-2.

Leo you are correct. All my jets are matching and the same (thanks gggary) as what came in my rebuild kits with the exception of the needle so I think I will use the old needle again replace everything else and do a good cleaning.
