OP
I’m just now after a year, understanding tuning and that’s with guidance from a friend with a lifetime of experience.
It’s all good and well trying to follow a method, but the issue arises when the saw starts to do something you didn’t expect.
Say you go to 500rpm + spec, you find lean drop off and then richen it up, it may bog off idle still. Then what. Well you need to know if it’s a lean bog or rich bog. Does it splutter or dip? What do they sound like? You adjust incorrectly for one and then you are chasing your tail.
Then you need to know how and what to adjust to get it right. Then you go WOT, but if you don’t understand what 4 stroking is you really are asking for problems. Then you have a saw that wants to stall on return from idle but unless you know if it’s L or H you’ll chase your tail. Then your saw Starts to die at idle, so you increase idle, but what if your L is too lean or too rich and butterfly is not the issue. If you don’t know what to listen for it’s tricky.
Also, tuning with a saw that works as it should Is one thing, but what if you have an air leak, but you don’t know it. Tuning will go out the window and you’ll start chasing your tail again.
For the guys here who are experienced they will know, without thinking, what to do. What’s often forgotten is that an untrained ear doesn’t know anything.
