I am just putting my buggy back together after a 6 month rebuild and now the motor starts to cut out pretty badly if I give it more than half throttle. It starts fine, idles fine, and will rev to 5k-6k, as long as I do it at 1/2 throttle or less. I was hoping it was old gas, but I have ran it for awhile without much change.
Could it be the fuel pump (E8248)?
Is there a certain fuel pressure I should be looking for at 1/2+ throttle?
