I have an Echo BK400 that's been in the family for a long time. It has been great. The last time I used it, it began "surging". I'll be using it wide open and it will act like it's stalling out. This lasts for just a moment, then it runs again. The longer I use it the worse it gets. From cold, I can use it for 30 minutes before it starts acting up. When in happens I can see the choke lever move towards choke. I thought it was a weak spring, so I tied the choke in the open/run position. That didn't help, but I thought it might provide a clue. Unfortunately, I'm clueless. I tried cleaning the air filter, and that didn't help. Any suggestions are greatly appreciated.
Thanks in advance,
Tom
