Warranty (builders) for a Ported saw

[michaelmj11]

The biggest issue I have is with people that have no idea how to tune their saw.

They ask me if I can tune it for them before I send it back.......

No.......I cannot.

As elevation changes......air density also changes. That means the carb will need to be adjusted.....

I can tune it so it is perfect today, at this temperature, and elevation. But a high performance engine will need to be tuned daily for the owner to realize it's full potential.

Heck I'm clueless about tuning, thank God for m-tronic.

I have read where most people tune it by sound? Something about it sounding like a 2-stroke at one point, and a 4-stroke at another?

A saw really needs tuned every time it's used to be running correctly.

I don't want a saw I built fat but I don't want it lean either,I always ask if the person can tune one or not.

Most people dont know how to listen a saw they are happy when the saw screaming like hell crazy they cant recognize what mean rich or lean, this is the firt lesson i believe that they must learn
some others dont know how a saw react if it have leaks or problems with the coil or filters problems and they go directly to the H and L with catastrophic results most of times

The ability to tune a saw will give you most power all the time with no danger of failure.

I was working with a guy who couldn't tell the difference in the saw when it had the chainbrake on, and when it didn't. (I had commented to him that the person who's saw was making that noise/sound either was stuck/pinched or had the brake on)... dude next to me went "huh?"


And I can't tell what a saw sounds like with those other problems. ... course I've never had those problems so....

Sounds like a great idea, I would be all in favor of moving this thread, if that was your gist.

Carb adjustment is quite simple when using the system I devised all by mineself.
Assuming the saw has no other issues and the filter is clean and the saw is warm, do the following:
Turn in the high idle (LA) till the clutch engages (chain turning).
Turn L in or out until highest rpm is found, then back out L a few degrees, goose saw to see that you get the best response. Repeat if nessesary.
Back out LA until chain stops turning.
Lastly, turn in H to get a setting on the edge of 2&4 stroke. Then back out H a few degrees to find the sweet spot.
A saw needs fuel when in the cut, so run it on the fatter side of lean.
A tach is useful when doing H, so as not to get into a lean sitchiation.

Not my meaning at all. I just wanted you guys to see that thread.

You'll never have to wonder what I'm thinking. lol

Ok, is there a video somewhere, or one that you have, that shows/demonstrates this "edge of 2&4 stroke"?

I just want to tell to all theese peoples that they afraid to porting theirs saws , Dont be afraid to porting yours saws , if you decide to do it do it , its not nothing that will hurt or destroy they saw , theese *f-wording saws can work 24 hours a day in extreme conditions without problem ( stihl- husqy ) tests .
So find the builder make a good deal with him and port your saw , and if something go wrong its not the end of the world a new part and the problem solved

if you read a service manual you see the same procedure of the above is about for all saws that are in the earth this moment

And the manual describes how to tell the difference in 2 stroking and 4 stroking?

Then you have the general *pretty boyes, like me.
I had never ran a ported or modified saw, so I really didn't know what to expect.
The difference was day and night, of course.
I was freaking out so much, I actually thought something was wrong!
It was just going through my head, WTF this can't be right.
Nope, nothing wrong....just that's how the saw is now.
It just came back to my ignorance, of not knowing exactly what my expectations really were.
If that makes any sense?
Thanks for putting up with my dumb questions.

No, I'm on the same boat, it is why I had asked about a YouTube video showing both / the differences

You must training your ears for this

 

[jmssaws]

The difference between 4stroke and no 4stroke is night and day. If you don't know if your saw is 4strokeing or not,it is.

A lean saw will make the hair stand on you,anybody that can hear should easily tell the difference.

I tune every saw the same,after its completely warm.
I turn the low in to lean surge then back off just from lean,check throttle response then set my high to a slight 4stroke then check my low again by leaning it out then back off just from lean. Turning the low in you will hear the tone of the saw change when it leans out. Turn the screws slow and very little. Most that can't tune a saw turn them too much and too often.

I am open to suggestions as to how... Sincerely, Earnestly, Seriously.
