Hello new to the form
I have twin 2001 Honda bf130s. When I run them at WOT for more than 15 minutes one of the motors drops from 5,6000 RPM to 4,000 and surges a few hundred. If I back off the throttle to.. say.. 1,300 and wait 2 minutes it will do the same. Now to what I have done:
Spark plugs
New recor and fuel line
Ran on 6 gallon tank
Every filter changed in engine
New LP fuel pump
Swapped injectors
Compression check is strong and even on all cylinders
Also rebuilt HP fuel pump and VST
Changed thermostat

I'm lost
