    Anyone have a source for one? Someone I know was trying to tune a Husky 330 trimmer and the regular 4mm, 21 spline tool does not fit. Research shows me that I will need one for my as of yet unused 525 trimmer, so I'm looking to snag one up.

    OEM Husky number, will take any aftermarket also.

    HUSQVARNA 598846901 - CARBURETOR TOOL 20 TOOTH 5MM - ORIGINAL OEM PART - NO LONGER AVAILABLE

    I think that was the same set I bought. If memory serves me correctly maybe 15 - 20 bucks for the set.
    Certainly not Snap-On quality but it worked for me. I needed one for Stihl.

    Sounds about right. Has 10-12 different styles if I recall.

    Many I probably will never use but not bad to have in case the need comes up.

    Have two of those. The spline drive in them is 21 tooth x 4mm.

    By the way, I found out that a pacman will work, but not very well.

    Ordered a chinesium one off ebay. Little skeptical due to lack of description or pic of inside of the bit. Now we wait on the boat.

    Interesting. The one I have worked on my Husqvarna 543xp andva 390 I recently worked on. Unless saws are different than other Husqvarna products?

    Appears some stuff has it, some does not. My 525 seems to be affected. I have previously always been able to use the Hipa tool on anything from Sweden. I'm not keen on having a 'gap' in my adjustment tool stash.

    Idk i think i would just slot both adjustment screws on all the saws i owned and use a small flat blade screwdriver on um. Would make life much more simpler.

    You figure the epa is why we can’t adjust carbs anymore even though we can tune the equipment to run the best for the changing situation the tool is in

    Gotta love government overreach. They keep treating everyone like they're stupid and everyone will be stupid.

    Like we arnt competent enough to tune a saw to the ever changing weather conditions. Oh heres this electronic carb that will do it for you cause your too stupid to do it yourself. Oh that didn't really work so here's a saw with a fuel injector. Can only imagine the problems that'll be had with that tech in the future.

    Carbs are cheaper to clean that replacing fuel injection components. Usually they can be cleaned same day without needing parts.

    This little rant has me thinking. Do those new fuel injected saws have a fuel pump in the tank? I think that's what most powersports didn't when they went fuel injected.

    Not having to pull needles is even simpler. Unsure why this particular tool is extra elusive. They'll be easier to find if demand kicks up. IIRC I had to get my first Husky spline tool out of Europe via Ebay. The Hipa and other kits were not yet prolific at the time. The first kit of tools I bought did not have the micro D in it, so I bought seperately because my pole pruner requires it. Now they come in the kits. Seems like they'll need 48 different drivers by the time another decade passes.

    No standardization is what the real issue is. "We're gonna use this driver." "That driver is nice, but we like this one better." "No, this one is best and what we'll use!" Seems a little schizophrenic considering there are only two main brand names of carburetors in this genera.

    New engineers have to put their mark on a product. :headbang::doh: Saw it when i worked for chrysler. Every time someone bought us stuff changed. First i experienced was Daimler and then Fiat.

    Was in a chrysler training class once and the instructor was talking about the new engineers coming there for hands on training. He said there was one student they all called gramps because he was so old compared to everyone in class. Bet you can't guess his age. Was supposedly 25.

    No wonder new designs stuck. They have kids working em. :hair::hair:

    Personally I think a BS in Engineering should require 500 hours of hands on mechanical repairs so they understand.

    From what that instructor said they need none! He said for most of them that was the first time they held a tool in their hands. He also said that class was rebuilding transmissions and one of the students slipped while working inside the tans case. If you don't know, everything in there is super sharp! Iirr, that was the first time that kid saw his own blood and ended up passing out. Had to go to the hospital and get several stitches.
