First post here, haven't been able to find any threads for this specific issue and none of my buddies can seem to figure it out. Truck ran great up until a couple weeks ago when I pulled the pump out to put new shaft seals in. Doesn't seem like it has full throttle anymore. Took some time to get the timing dialed in, now runs fine at idle to around half throttle and then just stops adding fuel. Also loses all clatter at full throttle. Throttle response is very slow. Added a couple extra flats on the fuel screw, which it didn't respond to either. Ran it for a few seconds with the top cover off just to confirm the metering valve has full travel, which it does. Currently at a loss of ideas. Didn't have the head apart at all when the pump was off, no idea what I could've screwed up.
