I Have an 05 270 FV with a VP 8.1 and I'm puzzled.....as I get in the 3500 RPM range I get a momentary ignition interrupt and 2 beeps, it now has become fairly persistent. I changed the fuel filter, that didn't help. What really puzzles me now is I have also discovered that moving the trim button, either up or down will also cause the same interrupt. i have switched batteries, no change.
Thanks for any advice.
