Throttle and choke springs

Can someone post a picture and description of the throttle return springs and the choke springs? This is for HS2 carbs on a 1275.

How many springs for each application?

What do each spring type look like?

I'm trying to verify my setup.

The three that go to the heat shield are all throttle springs. The choke springs are on the carbs. Correct?

I'm not sure. My setup had two springs on the throttle and two springs on the choke. All four springs were connected to the heat shield in the outer of the 3 holes. There was no spring from the center of the throttle shaft, though there is provision to use one there.

Three springs only on Bugsy my '68, I think MOSS Shows three in their catalog. Definitely 1 in the center hole.

The factory normally sets them up with tow on the throttle and one on the chocke linkage, but there are many ways to skin this cat, so you don't have to copy the factory and I normally do not. The choke lever arms is already sprung on the side lever, but all factory applications still put atleast one return spring on the choke linkage bar, old racer's trick to use two to always insure the jet can't drop duirng high rpm, where vibration is at the most, it can and does happen. I normally use two on the throttle linkage, one at each throttle linkage lever arm (none in the center), since the throttle has no spring in the side lever like the choke, I prefer two, kinda like a safety back up system.

Thanks, Hap. What you described is what I had previously on my setup. Just wanted to make sure that was a correct way to set it up.
