Moddin my 026 muffler

[Bowtie]

Just started moddin my 026 pro muffler. Should I drill the holes on through the outer piece and the baffles, or is this all I need to do? Tell me what you experts would do. Information only this saw is stock except for this mod, no porting.

Here is a better picture.

IMO, you got it! you may need to adjust your rpms.
Your saw will also rev a little quicker also. Looks
like a good job.

What carb is on this saw ???

Looks good. Mine is similarly modified, but the entire raised area that you have opened up has been more or less shaved off. Not sure if it needs to be as severely opened up as mine is, but it came to me that way and has always worked fine...might as well leave well enough alone.

No need to go through the baffle, too. It is nice to get the exhaust off to the side, so I'd leave the outer baffle unmolested.

All you really need a a couple of 3/8 holes, one above and one below the existing hole. Inner portion only...

Its a Walbro carb. I didnt find the model # and didnt want to tear the saw apart to find it, as it runs well.

Soon as my tach arrives, I'll be able to set carb and try it out. Im anxious to get the bar buried to see how she works. If Im satisfied, Im gonna mod my 034, since Im still waiting on a damn carb kit, fuel line and impulse line. 2 weeks to get it ordered in, and still aint here! :taped: Thanks to all of you for your opinions and advice.

Hey all, i was just messin with my 026, and noticed there is no adjustment screw for the h setting on the walbro carb. Is this gonna be a problem since I just modded the muffler? Im searchin as you read this.

That is why I asked which carb you have on there......I will let Lake fill you in on the details...

I read your post ultra, but I already did the mod. If I have to I'll get a different carb. I saw the hole for the h adjustment, never thought to look closer. Tried to adjust and realized there was a white rubber housing that blocked the h adj. and behind that is metal.

Just did one on my 026 pro last week.. Put a Walbro WT-194 works great and has alot of adjustment..

Do I need to yank the carb and see what model it is? Or is it obvious to you guys I need another? Thanks Ultra

The carb comes out really easy ...Do you have the shop manual for it???

[Bowtie]

No, I dont. I bought the saw used, and it came with nothing.

 

[Bowtie]

i know I can get the carb off, just wondered if it was crucial or helpful to know the #s if its useable.

Check your PM's

I believe I can download the manual off stihl's website. I'll try that route.

Generally no... the factory setting is usally quite rich, often about 12,500, so you might be just fine with the muffler opened.. but you need to check it. 14k is max.

Only the user manuals, not the Service Manual or IPl.
