Search done but I still need help to ID carbs

[McDog]

I read on one thread that mikuni carbs have their size stamped under the fuel pump. These mikuni carbs have:

2
33
75
MAC

stamped on one and:

2
It's scuffed but I think I can see one 3
76
MAC

stamped on the other. Do you think they are 33's?

Is there something I can measure?


Any help would be awesome:dunno:

Take one off the manifold and measure it's diameter at the bottom. I'm guessing they are 44's.

You're right, the bolts on the flame arrestor plate threw me off. I can see there are only 3 underneath now.

It's like you guys are speaking your own special language. If I measure the hole in the bottom in mm's it will be the size of the carb?

Yes the bottom of the carb diameter in mm's is the size.
