troubleshooting help stihl 260

well, you were close, I did swap the plugs and didnt fix it. but, .I am happy to report that I swapped the ignition coil out and it started right up and ran strong. The spark that I was getting was too weak, the wire had a bad spot on it and the coil from parts saw fixed all the problems. thanks for all the ideas, they were helpful. I was thinking it was the vacuum but this is much easier, i now need to decide to get and OEM coil or aftermarket.

Before you toss the old coil you might want to replace the HT lead and plug boot if it is damaged / cracking. The existing wire should just unscrew. Also replace the boot on the coil tower if needed.

good to know, replacing wire is probably all that is needed.
