Runs good! Often those little things involve a lot of swearing

I am certain that I will cut the muffler open when I get to modding it on my PS-9010.

6100 troubles!!!


I bought my 6100 new this year (it's a 2012 model though). I may have ran 3 tanks through her so far, but here is the deal. I tried to tune her a million times by now because at full throttle there is a small delay. Thought this might be the reeds that have to loosen up over time, but then I found out that adjusting the H screw that the delay becomes much greater when I turn it in. So it doesn't get enough fuel I thought. Turned the H screw way out and it is better now, but there is still a small hickup when I rev it.

Looked up the factory settings and it should be L 2 1/2 turns out and H 1 1/2 turns out.
I have the L at about 2 1/2 but my H is 3 turns out!!! Turn it in any more and it looks like it's getting to much air and not enough fuel. I can turn the H screw out further, but it doesn't matter how far I turn it out, I can't seem to get it to fourstroke in the cut. Thought there might be an air leak somewhere, but the saw is brand spanking new. Tune all my saws myself, even other people's saws. This is the first stratified engine i've done though.

Is it the carb or am I looking in the wrong direction here? I really want this saw to work perfectly, because it should become my go to worksaw along with my ps420.

Any help would be much appreciated.

Tamper resistant carbs are DUMB

I agree. I always take out the H screw on the “Dolkitas” and slot it with a dremel cutoff wheel. That way if you loose your special tuning tool, your not screwed and can use a screwdriver. Options. Lol

I like it. Should be simple to adjust.
I can tune the Stihls, just can't tune the Dolkita's. [emoji848]

Cheap carb screw driver kit off eBay does the trick, mine is a 8 pcs with a pouch.

Nice 115 with heated handles, but she's not an "i" variant, isn't she?
Would suite my tiny collection quite well.

yes it was a nice saw and no not the I model they don’t come around very often

Hey huskyboy, was it an hour well spent? How much louder is it now?
The original outlet is tiny compared to the size of the exhaust port (13mm round vs 15mm x 27mm).
I have been thinking about doing something similar to you, but I don't want to hack up a hard to replace muffler if all I am going to get is a louder saw.

It’s definitely louder. Not terrible though. Worth the gain to me gutting it as much as possible. If you don’t wear hearing protection I wouldn’t do it. You can always do a milder opening if quieter is what you want. Just drill two holes in the end of the baffle through the exhaust port with a 1/4” drill bit, open up under the deflector a little bit and reuse the spark screen.

Where did you notice the gain? More low end torque, snappier throttle?

More power in the cut overall I’d say. It had good torque before yes, but now it has a little better rpm and a little better throttle response. Tons of torque.

I picked up a nice 116si last week which had a scored piston due to a base gasket leak, I think, fitted a new Meteor piston and on fitment new piston hit the crank on the skirt as the piston was not machined correctly, unusual for Meteor but these things happen, so if any of you good people purchase any just check before fitment ( not like me in this case) see photos.

Is backpack or generator optional?

 

[Wilhelm]

Generator is mandatory for in the field, backpack is optional as You can choose to utilize an extension data cord as opposed to an extension power cord.
Wireless computer carb management is in development, probably a couple years out.
