That old tecumseh 2-stroke was about 80cc but made just 3 horsepower.

I put the 144 on a 257/262 and it runs great. It was running a 120. Now the high idle catches and releases, everything adjusts as it should and the saw revs up quickly. I did not put the saw in the wood yet. Unfortunately I broke the sealing collar in the process, but my no-accelerator-pump 144...

Remember that the initial problem was setting the high idle. The saw was running strong. It was only while fiddling with carbs that I discovered the leaking seal on the clutch side. I have others carburetors I could install in the 261-1/2, but now I am dug in on this peculiar 144a. I pirated a...

OK but I never found the Husqv ipl that includes the piston version. What magic did you use for that?

Thanks Barry. Can you tell me how to get from the generic diagram to the Walbro part numbers?

I still don't know the numbers but a Husqvarna customer service person on the phone said it will reply tomorrow to my request for those part numbers, parts 54 and 9 on the walbro diagram above. Many years ago I bought fuel nipples for HDAs directly from Walbro, but I am not seeing how to do...

Parts are not available through my husqv dealer. I wonder if there is a way to get them from Walbro. Any suggestions?

If the idle screw is set so it just touches the butterfly throttle plate stop, and I then I adjust the L mix screw for max rpm, or leaner, how do I get the revs back down so the clutch is not engaged?

The newest ipl I see is 1999-06 and it does not show the flat on the shaft. Maybe I could delete the piston, plug the port and use the readily available shaft 503944201. Or just use another carb.

If I get a new shaft I will also replace the piston assembly, if available.

Which is softer, the aluminum or the brass? I guess it varies for each alloy. Maybe I could measure wear in the bore if I can find the right size drill.

Yes. Maybe I am too redneck for this neck of the woods.

The saw is 01 2500116, so about the end of the line. It looks to me like the wear is concentrated in a small area of the brass and it would be broadly distributed over the length of the bore in the aluminum.

The carburetor is a 144a . Further searching makes me think it is the piston for the accellerator. It shows on some diagrams as part 54 but I haven't found a husqv part number. The spring and piston sit in a hole perpendicular to, and held in place by, the shaft. I will get some pics.
