Struggles after 4900 rpm

Thanks you for all the replys. Very much apreciated.

First thing today is to get new plug wires and check that fuel filter again. The hose coming out of the pump is going into the filter on the side marked "In" right now. That should be correct right?

I also thought about it being hot outside, but yesterday it actually was nice and cool outside when I tried it.

So today with new cables, and trying to go back one step at the time I will see if I make any progress and get back to you.

Thanks again!
