The 025 just has the grub screw in the piece of fuel line for a vent? It only restricts but does not stop air flow into or out of the tank

Yep 2 grubs is all. Thats all I checked before heading back in.

Need to check and see if any foreign junk may be blocking anything.  She was pretty nasty under the cover.

I've seen the vent side of the metering valve packed with saw dust

The impulse line on the 025/MS250 is sometimes somewhat critical. It is hard to see up under the poly air shield. But it will almost slip off the spud up under the boot and will cause the impulse to alternate between OK and bad. Almost need a hemostat to reach under there. The hose is better about staying on the crankcase but there is more heat on that end and the rubber will get hard.

Keep in mind that the spark plug and switch wire from the coil fit in through a little square slot just above the coil in that polyethylene heat shield. If the plug wire is brought up along the coil side of the heat shield and crossed over the shield to the spark plug near the top - the heat shield will wear the insulation off th plug wire where it crosses the heat shield.

Thanks for tips Jim. I smiled when I seen what it was.  Because I know who the local 025 250 guru is.  ;)

Just surprised in my haste I thought I seen 026 instead of 025 and still didnt catch it when I in a hurry popped air filter cover for quick look.  Oh well lesson learned to slow down.

Funnily enough I rebuilt an 0125 and 230 today with new bearings and seals on 1 the other needed a replacement case due to being run lots on concrete and worn thru the oil tank!

I always replace the impulse line with the common use 3.1mm I/d stihl fuel/impulse line. An extra few inches in length makes the world of difference when refitting.

If its a "c" model that has the fuel bulb also double check that but sounds like a minor blockage or slightly lean on the L as you both say.

That reminds me I need to order some more echo black 3mm x 5mm and  3mm x 6mm fuel lines to use for impulse lines.


Thanks.

The stihl stuff can also be used for fuel and impulse lines on Husqvarna saws like the 357/372 etc hence why I tend to buy it in 5mtr lengths  ;) ;)
