    I'm always trying to get a little bit more out of my saws. I have two 044s and two 460s and one 361 .I'm just curious about the different carbs if there is a difference in performance

    Thank you Ozhoo. Looking at the diagram, I would think the independent would be best but readying how they work, I think the dependent is the best. Very interesting how the placement of 2 holes make the difference. Thanks again. Cheers.

    Seems I cannot count. I have 6) 044's. The carbs
    1) Walbro HD17A
    2) Zama S20
    2) Zama S5G
    1) Zama S5E
    All also say Stihl on them.

    I’ll give you the quick and dirty I’ve learned, although it isn’t as comprehensive as what’s above.

    All HD carbs, exc the 361 carb and the 461 carb will physically fit.

    The 361 carb has no impulse barb, it’s on the face of the carb. It also has a smaller bore. A different choke rod.

    The 461 carb is reported to have a different midrange circuit. I can’t confirm this. I’ve visually seen a #58 and also a #70 jet on different HD50 carbs. They have an impulse barb but need the choke rod swapped or the control switch from a 461 swapped in to have choke function on the older 1128. I personally haven’t noticed any huge performance increase using it on a 44o/460/446.

    The rest of them all fit, all have the same Venturi and bore size, but have different main jets. The main jet is removable and easily modified with a micro drill.

    @ri chevy has a nice little chart he wrote up on bore sizes and factory jetting. In general, if you need your H needle out more than 1.5 turns for the saw to run in tune, consider drilling the main.

    The Zama have individually controlled Idle circuits. They run well and touching the L doesn’t affect the H tune. On the HD Walbro, adjusting the L will actually affect the H tune a bit.

    Above is my take on the whole thing. YMMV

    I’m sure I missed something or there is a caveat that exists.

    It’s a 5 minute job to make any jetted like an 8 or an 11.

    I’ll add that the HD14 is .7 also.
