Now that my Echo 501-P is here, and I have tons of hurricane wood to test it on, I am planning to fiddle with it a little and try to get good performance. Not looking to shatter records, but I would like to get significant improvement. I don't need to do this, but I want to do it for fun and to see what the saw will do.

I have a full-chisel chain on it, and I got a Gearhead deflector which has not been installed yet. I have not taken the tube out of the muffler yet. I was planning to add the deflector, take the tube out, tune it, and run it for a couple of tanks before considering anything else. I ordered a Proline tach because people in Amazon reviews said my $7 tach was not necessarily accurate.

I looked at the manual (for once), and it says the saw needs at least two tanks of fuel to go through it before it's broken in. It says the power will increase and the emissions will stabilize. Thank goodness about the emissions, because I was real worried about that. I was so worried I could hardly digest my soy.

1. The manual says the stock max RPM is 13,800. Should I be satisfied with that after the saw is opened up a little? I learned how to tune a saw, and I tuned my CS590, but I just found out I was supposed to take it to the edge of four-stroking, which I did not do. Should I just do that with the 501-P and let the RPM's land wherever they land?

2. Sooner or later, I may want to put this cylinder, or one from another saw, on the lathe. I have seen people using shopmade aluminum mandrels for this. I don't quite understand where they get the friction to turn the cylinders. If the mandrel slips inside the cylinder, I would expect the cylinder to remain stationary when the lathe is running because the parts would slip against each other. How are people getting cylinders to move with their mandrels?
 
Hello, I was really trying to get a discusion on saw building in this thread. But so far stone dead. Havent been any since trapper Mike was in 4 years ago. Have all sawbuilders quit?
 
Morning. The megaphone muffler is not on any of my saws. It was just a picture.

Tig welding works good on pipes, but you have to make all cones to fit perfect. This I have made.20241102_095002.jpg20241102_095125.jpg

It's been covered a few times so there's not much new stuff to post about.
If you want to build an echo into a strong work saw check out charles brisco or super dave outdoors on youtube. They build a good running echo and show exactly how to do it. Some guys on youtube are good at making videos but crappy saw builders but those guys are good saw builders who make videos.
 
I follow many saw builders on youtube. But it is only a few thats know wath they are doing. Chainsaw porting have change over the years, especially with strato ports and autotune. So there is many new stuff to talk about and discuss. There is many ways to get performance.
 
You're not wrong, porting a strato saw or auto tune saw is different but the echo 501 doesnt have strato ports or auto tune. It's built like a 25 year old husky, which is good in some ways and bad in others.
Wait until the guys figure out coil swaps on the auto tune huskys get them more rpm. My buddy put a 550 coil on his 562 because the coil went and he had a 550 coil, the saw gained about 500rpm and runs better lol.

I'd start a new thread on porting new saws, echo's are old school porting wise and already dialed in by a bunch of people.
