Thoughts on advancing the timing on the Echo CS310. Anybody having done this, and if there was an improvment in performance.
Well it's gonna be one or the other, cast into the flywheel or seperate key. For me I hope its a seperate key to allow me to make an offset key, but if it is cast into the flywheel I can work around that also.Yes, they do cut well for their size. I was pleasantly surprised with mine. I was thinking about the advance as well, that's why I was researching it. I haven't pulled my flywheel, does it have a separate key or a cast in key?

I think he means it's already set at 30 degrees with the factory position of the flywheel. I think some coils can retard and advance. I think they retard upon starting and advance when running. I have read that advancing over 30 degrees can have negative effects, like hard starting and overheating.Well it's gonna be one or the other, cast into the flywheel or seperate key.

I don't know what Mountain Lake means when he says it's built in unless it's part of the coil design. I sure if you advance the flywheel your going to move the static timing forward allowing the built in timing if that is what it has to continue doing it's own advancing.
I wish I knew. I have only done it on an old Husqvarna 50."I think he means it's already set at 30 degrees with the factory position of the flywheel. I think some coils can retard and advance.

Ah gotcha.... so if it is? 30 degrees, is that already considered the max for that engine design or can one bump it forward lets say 5 degrees more???
Were any of them echos?It’s probably a cast key. Give it a try. Worst case you just dial it back to stock. I know the other small saws that I advanced liked it.

I agree, just curious.No
Worst case he’s out a half hour of fiddling around.
When you say SAI2 modual is this contained inside the coil or a seperate unit ?Echo has used their digital SAI2 ignition for years, instead of having a set ignition angle...for example...the ignition happening at 21* btdc which allows for easier starting, but is not stellar for higher rpms where the timing curve retards. The sai2 module retards the timing at starting speeds and steps up for a healthy idle...then as speed increases it rolls into an advance for power. Sai2 is 2nd generation Slope Advance Ignition. They may be on a 3rd generation by now

Its all one unit, some versions contain a rev limiter as well.When you say SAI2 modual is this contained inside the coil or a seperate unit ?
