I have a 26EFI with 1300 hours on it and I have noticed that it will drop power and then regain it. That does not happen alot or consistently but it is noticeable when it does. It almost seems like if the seat switch is opened but it happens both when the pto is engaged or not engaged. I am thinking some type of fuel delivery problem that is intermittant. It also smells like it is running rich at times but that just may be me over analyzing the situation. I hate intermittant problems when its broke I can get it fixed but how do you diagnose sometimes broke. Thanks for any help you may be able to give.
