Jim did any of those older 025 you got from me have 2 piece mufflers?

Somewhere along the later production of 025's the two piece muffler was changed over to the crimped design. Comparing my two piece and one piece crimped flange mufflers, the dog house is the same other than being captive in the later crimped design.

Looking at 025/MS250 used mufflers on Ebay, there are several iterations of how the outlet hole(s) (is)are cut under the outer front cover. I go in and make it one big hole as big as the depression anyway.

The main advantage of the two piece (non crimped) muffler over the newer style muffler is that you can get the dog house out of the two piece muffler and open up the holes. With the crimped muffler you have to reach in on the engine side of the muffler to open up the dog house holes.

The main advantage of the one piece muffler is that if you let the muffler get loose, the muffler doesn't come apart at the seam and burn a hole in your oil tank.
We should share what we know... someone may learn...

That early flat air filter is hard to come by? The current ones set in a 90 degree adapter and all you see is what looks like a small loaf of bread for a filter.
That's the airfilter they sell now. There were two different ones before that one. One is flat and fastens up against the carb with those aluminum barrel screws. And the very first one fastened in the cover.

There's no reason you cannot use the present day filter. But if there is nothing at all on the carb, you will have to buy the 90 degree elbow too which HLS also sells.
You get a lot more RPM with that nylon mesh filter than with the flocked version that HLS sells.

Oversize stud repair for stihl 025 250 = 1123 664 2405

Copy paste stihl tech info below.

If the Standard Collar Screw is part #1127 664 2400, DG 8 thread, use Oversize Collar Screw part # 1127 664 2410, DG 9 thread, for 1127 series saws such as MS 290, MS 390
Installation:
If the thread has been stripped, the damaged mounting hole in the engine housing already has the required diameter (approx. 8 mm) and does not
need to be drilled out. Coat the DG 9 thread of the new collar screw with Red LOCKTITE 262, or equivalent and apply it squarely to the bar mounting face.
Use an 8 mm stud puller to install the collar screw into the engine housing and tighten down to a torque of 16 Nm.

If the Standard Collar Screw is 1123 664 2400, DG 8, use Oversize Collar Screw 1123 664 2405, DG 9, for 1123 series saws (021, 023, 025, MS 210, MS 250). It will also work on the 1130 (MS 170, MS180), and 1132 (MS 191T)
install same as above.

An oversize collar screw, part number 1115 664 2405, is available for alloy housings that have been stripped. The damaged hole will need to be drilled out to 8.5 mm (0.335 or letter drill Q) and rethreaded with a 10 mm by 1.5 pitch tap. Coat the threads with Red LOCKTITE 262, or equivalent, and install with the stud remover or use the double nut method. This collar screw is for the 3003 bar mount.

Compliant was smoking.

Found the bar tip was smoked and the chain was running beside the sprocket tip it self.

Also the oil tank plug missing from under the right side muffler area.

Reading up on making a plug without blocking the outlet hole to bar oil area.

copy paste info finding

Its suppose to have some sort of plug , I'm not sure what it looks like. I just made my own plug. But you dont want it to long cause it will block off the oil passage to were it oils the bar.

It looks like its suppose to be molded in with it . Doesn't look like its really suppose to come out. 

Just thread in a fine thread set screw in it

plug it

This is the pressure side, not a tank vent. Very short threaded plug with a dab of loctite

Yes, but no need for loctite. Thread in a very short grub screw. Too long and it will block the exit hole. An exact part from Stihl is the 090 vent grub screw.. 0000 951 5815 -25 cents MSRP.

Found the grub screw is sold in a tank vent kit.  https://northwoodsaw.com/store/index.php?l=product_detail&p=2070

Replacement tank vent for Stihl models 08S, 070, 090, 090G. Includes grub screw.

Replaces OEM: 1108 350 5800 and 0000 951 5815  00009515815
 



Thinking a 1/4" grub screw will work too.
