No insult intended, but are you sure it doesn’t have spark? CDIs are not all alike, but most of them have a real thin white spark that you can’t even see in daylight. When my chainsaw wouldn’t start, I checked for spark and would have sworn there was none. After spending way too much time on it, I realized it did indeed have spark and there was some other reason it wouldn’t start.
My Johnson will throw a thin white spark an inch long with ease. But the chainsaw is more like an eighth of an inch and real thin.
Hate to admit it but "somebody" wasn’t paying attention and filled the chain oil tank with fuel and filled the fuel tank with chain oil. Sheese, what a dummy.
