I have a BC1600 that supports multiple attachments. I've been using it for a little
over 2 years now.
While I was using it the other day, the engine started dying down/revving up when I
squeeze the throttle. The engine
starts and idles fine.
Whenever I hold down the throttle, the engine will die down then rev back up
repeatedly. It enver cuts off, but as soon
as it gets to the max RPM, it slows down, then goes back up.
There isn't an abnormal amount of smoke coming from the trimmer. I replaced the spark
plug and that didn't help. The old
one was pretty fouled up. The manual said to adjust one of two plastic screws located
near the fuel intake, but it was
already in the fully adjusted position.
I used the proper oil/gas mixture on the last batch of fuel.
Any ideas on what could be causing this ?
