Husqvarna 162, 2x 266, 268 Frankensaw Project

If I add a second port to the 268 muffler does it make sense to put it in at an angle on the other side like I am holding rather than in the front so the exhaust bursts have to contort to get out and blow straight out from the cylinder through a hole in the front?

I also dremeled away at the melted hole to make it look okay and ground away the dripped down crap on the other side to keep the air gap and flow between the muffler and top cover.

I believe so, but I can't really prove it. Regardless it looks better.

Strike 2 for the Chinese parts. One of the three chain brake flags now wants it's natural state to be back and in contact with your hand. Haven't opened it but it has less than an hour of run time and it shouldn't do this. I think the goofy spring shoved up in the flag is supposed to keep it forward against the trip lever. I have this random old orange flag that came in a 65L parts saw box I might use it when I take this apart.

On the way to remedy strike 1. 268 muffler ready for bead blast and then brazing. Added the port and will braze the two halves together as well.

So I think the issue with the chain brake is the goofy spring in the flag. It is supposed to be all in one plane so to speak or at least parallel planes but this one clearly has taken a set to the side. obviously not spring material, just wire. I guess I will have to cannibalize the husky 41 extra clutch cover for its spring.

Ouch. You got a rough deal on some parts. You'll figure it out. Great job on some nice old saws tho.

 

[briantutt]

For future reference goofy spring goes in this orientation, then put the pin in to hold the spring in, pin goes full under the spring not through either loop.

Got the 268 muffler double ported and tacked in the corners. Also brazed the center through pipes to the front half. Shouldn't go anywhere now! Just need to grind out the excess so the bolts go down the pipe and then ready for some paint.

268 back together. Had to shape the top cover a bit to clear the new port.

Churched up the three clutch covers with some assistance from Sugar Creek Supply.

Got a load of oak and ash today. The 268 and 266 did most of the work (well the Johnny 590 did some limbing)

such a good tip to not predrill when tapping up to the next size screw. Just fully tapped to M6 one of the starter mount screws on the 162. Just have to back out the tap when you feel a chip load.

Got this today for $9 it has a collet so it should work for the magic emery cloth cylinder cleanups in the future.

These will come in handy for the next project only $5

Where did you find them?

Hey guys. I know these saws come with several different carbs.

Is it a bolt in replacement to go from say a 163 carb on a 266 to a 260 carb on a 272 or do linkages need to be changed as well?

 

[briantutt]

all four of the ones I rebuilt you could interchange.

I don't know the answer for sure, but believe you need the 268/272 intake as well as the carb (+ the cylinder of course) for a direct bolt-on, without having to modify anything.

@Cantdog, @spike60 and @taplinhill will know the answers for sure, and likely others as well....

Edit; Forgot to say, if you just want a 17.5mm carb on an older 266, the HS-224 is a direct bolt-on.

 

[briantutt]

agreed, the air filter intake parts are different but the linkages for throttle and choke are all the same.
