Re: Universal M25 losing power
I don't see anything regarding bleeding the injector, distributor,pump. That would definitely cause a loss in high rpm because it is connected to the governor.there is a bleeder valve on the side of the injector Pump a 5/16 wrench should fit. Loosen this fitting and pump the hand lever on your fuel pump until absolutely no air comes out of the bleeder.only diesel fuel tighten the Bleeder This is not mentioned in your video...... hopefully this is the problem. air can trapped at this point when you change fuel filters or run out of fuel.
