??? That is not how they look in the part lists (Husky and Walbro). Maybe someone has tampered with it?

The issue with the HD-6 usually is just that it has a smaller venturi than the HD-12 (unless there are a misprint in the Walbro part list).

The Walbro HD-12B is made the same way in the idle circuit. Those extra holes are metered by the idle circuit needle valve. Also they are uncovered by the throttle butterfly as the throttle is opened. At lowest idle, they do not work.

Okay Thanks, but why so much fuel that the H-circuit is overruled ??? now it runs like it has a fuel RPM limiter on it

The Walbro HD-12B is the standard carb for the 371

Well, I'll have to check and see. What I did was put my ported 371 top end on a 365sp bottom end because the 365 was a very low hour saw. My 371 bottom end ran fine, but since I had the low hour one I went with it. I also decided to switch the carbs because the venturi on the 371 carb was noticeably smaller, so I will have to have a look at the the carb that I swapped out to see what the number was.

Little something I found on the zama 362 365 carbs.  I ran them on 372 too.

Zama carb has smaller venturi  too. But on a work saw I never noticed a difference in them in the cut on a stock, muffler modded, woods ported work saw.  If I hadnt told you it was running a zama you would have never known the difference.

I think dozerdan had done the same testing on woods ported work saws between zama and walbro HD12.
