What are folks looking for with this. Good cutting obviously, but are they looking for an rpm, a sound, or general performance. It seems that the best performance in the wood would be a little lean. I have only tuned by tach or ear while not in wood. Maybe I'm missing something.
Tune by ear,not in the wood. Then run it in the wood & see if it likes to eat. Will have a "steady growl" more than a wide open scream If no , adj a little at a time , then back into the wood.
I tune the old 041 on the truck bed, when it starts to stumble WOT back it down a touch chain speed should be lower when I'm laying on it and always appears to be at optimal power. I have to tune from seasonal changes due to elevation and the swings in temp - could be 80-90F or 30-40F here with 40:1 mix in the old stuff. 50:1 can for the weedeater and blower - that is clearly marked for the GF to use
I am the same way, I do adjustments by sound. I've been cutting with my 455 for 6 yrs now and know it well enough to know when something wrong (or good)
General performance really. But there are so many contributing factors here. If the chain is sharp and the wood is decent size, the engine should run with a clean growl while self-feeding. If you have to apply pressure to get it to quit 4 stroking, it's too rich, or the chain is dull, or the wood is too small. Brad Snelling (blsnelling) did a pretty good vid on tuning with a load on YouTube. I think this was it --
