The tuning video thread

[davidwyby]

I keep forgetting to post this.
Fire away! Tuning in wood, tuning for different conditions, different length bars or chains. Post instructional vids or vids asking for help.
I’ll add some later as well.

I have seen some good ones, it would be nice if they were all in the same place.

I reference this one with new saw mechanics.

What we really need is a video that shows a chainsaw that will not tune properly and why. It seems most of the new guys and even myself get confused when a saw doesn’t respond properly.

I would be very interested in a video for tuning in which the saw is mechanically fine but the carb is not. Symptoms of a dirty or passing metering needle, leaking pump side seals and bad or passing check nozzles. videos for this information are few and far between!!!!
So you master carb experts, you wanna purposely put in a faulty check valve and show the before and after on a saw that is mechanically sound? I’d be willing to donate money for parts

Haven’t gotten around to putting vids up yet. Mine I’m looking for input more than giving instruction.

Just remembered something I keep meaning to ask: if you have a saw (grunty ported limited coil) that keeps hitting the 4stroke when you lift even the slightest bit, how do you know when to lean it and when to make the chain more aggressive?

I’ll be following this thread. I figure I’m about due to treat myself to a 372 clone.

...another question. I have a couple saws that don’t maintain a steady idle rpm. Where does one look next in that case?

Thanks

Air leak or carb

Air leak or carb

Coil sometimes too.

Getting used to a new ms461. The tachometer hates it. Four gallons of mix so far. Tuned in the cut with an occasional burble.

I'll toss this question out there, why can I not hear a clear "burble" on some saws? My brother's muff-modded, ported 365 has a very noticeable burble but other saws I've run don't. I can't name models off the top of my head, but some saws have a very noticeable burble while others never seem to 4-stroke.

That will be the limited coil pissed it off on mine put a 660 coil on tach works now and very easy to tune

I used this very video after Kevin built a saw for me. Now I tune all of my saws and am much happier than when I first started using chainsaws and was afraid to turn those screws. If only cars were as easy to work with!

I just had that problem with my 066. Ran fine when I put it up, went to start it and it wouldn’t run long no matter how I tuned it. Checked the spark and the coil was pretty much dead. Swapped the coil and plug, viola

It’s not too bad if you know what the screws do. And realize when fiddling with the screws isn’t gonna solve the problem.

Did the same to mine works well. Also got rid of limiters tabs in carb.

I think the main reason is how restricted the muffler is, and to a lesser degree port timing. Stock mufflers can be so stuffed up that there is little difference between 2 & 4 stroke sounds. Hearing protection may help filter out high frequency noise, so you can better hear the 4 stroking.

Same here I did the coil , TA ,limiters .

Send me kit for an early 084 HT 7A carb.

If you want to see the difference a good NOS 7A vs a who knows wtf is wrong with the original carb on it that would be a good video.
Might just need a kit due to stiff soft parts or maybe more is lurking in there. It absolutely will not hold a tune, idol or cold start properly. Big giant PIA! carb. A quick swap to new made it all better.

This would have saved my poor 346XS
