Hello--this is my first post-----
I have worked on small engines for over 50 years and have never seen an engine, of any type, that I could not get running----until now!!!
As many of you are aware, major changes and improvements have been accomplished with ignition systems.
That's where I think my problem is.
The chainsaw is a CS330t that was given to me by a friend. He knew nothing of the history. and the saw is in above average condition.
Here's the situation---
Compresson is 160#
Ignition spark will jump 1/4"--STRONG
Carburetor is new and getting fuel. No different then the Original that I rebuilt.
Crank seals passed test.
Flywheel key is good.
Muffler is clear.
This is the FIRST engine I have ever seen that will not make the first effort to start!!! Not even a "fart"!!!!! Not even with different volumes of starting fluid.
This absoluteny makes no sense and I strongly believe it is in the ignition.
I guess I would like a little education about how these new coils work and what controls the Ignition Before Top Dead Center?

First of all, welcome aboard. I think you are on the right track, The spark advance is electronically controlled so the only solution is replace the module. Oh, leave the starting fluid on the shelf. That is the worst stuff you can feed a two stroke. It dries and hardens the seals.

I have one of these a few posts below yours. It runs fine now after tweaking the carb for 2 hours. I don't know what we can tell you that you haven't already figured out yourself. I thought if the thing sparks and the carb works it should fire up. Too bad yours didn't. If you happen to retire the thing let me know how much you want to the chain brake handle.
