Looking for pics of vm30ss carb.   Inlet , outlet, everything you have.  

measurements on inlet and outlet would be interesting.  

Looks like I may have to use my vm 320-33 carb initially for my resto dt360.

while surfing ebay, I came across a carb that was advertised as a "Rt1 360 Carburetor".  After looking at it, I realized it was probably a
VM30SS.   I got it today, pics below.   It looks like an OEM VM30SS, including stock jetting.  The carb is in such good shape, I think I can run it nearly as is but plan to clean it, check float, first.  Need lotto ticket...unicorn found.

If original Yamaha, it should have numbers stamped in it across the choke boss on that model if I remember correctly. You should see it across the front of carb

Attached to the carb was an original throttle/oil pump cable. The dimensions were pretty much exact to the HVCycle's throttle cable I already put on.

That's a 1974 DT360 carb (445)
Original jetting spec was stamped "60" according to the documents I have. 
61 was likely a mid-production revision of some type.

Wouldn’t the older ones be flange mounted? That one looks like it’s clamped.
