hi. i have a prime mover l1300 the lift cylinder started to leak. so i bought a rebuild kit and instaled it . everything went well .today i put it back in the machine and now whene i try to use the bucket or the boom it moves slow . should i bleed the cylinder. im thinking it has air stuck in it . before i did this everythin worked good i took the lines back off the cylinder and it looks like they our pumping good . but what i dont understand is it has both line going into the pump at the same spot and a metal tube running from the front of the ram to the back. not sure how the air would get out . thanks for your help
