I have Been having issues with my
motor bogging - it happens about half the time running at full throttle-

The engine never stalls - it will run full out for half an hour then bog down the next half hour - it feels like the motor just loses pressure - or doesn’t deliver fuel - I can shift into neutral and blow it out full throttle without any slow

I have- changed plugs/ fuel filter/ fuel line to motor/ changed out all gas - rebuilt upper fuel pump - will change lower fuel pump this weekend -

I just am looking for anyone to give me their thoughts on this -
