Hey folks! We are having some difficulty with a late 80's Johnson. 99% of the time she runs great, but occasionally at full throttle, it will bog down and completely lose power. If we cut the throttle quick enough back to idle, it will stay running, and can immediately go back to full throttle. Sometimes, it will quit entirely, but then start up again with no issues.

We have checked all the usual and obvious items like filters, fuel tank siphons sucking air while on plane, gas cap vents being plugged, bad gas, water in gas, no gas :eek:, etc.

Any thoughts on where to go next?

Thanks,
Dave
