Our machine lost power today and stalled. Seemed like maybe a fuel filter issue? I replaced both fuel filters. I went to prime filters up with primer and noticed the rubber pump cover is dried rotted and shot. I remember awhile ago reading on here that if the rubber is cracked and ruined it will let air back in when trying to prime. I could get fuel to come out of the bleeder screw and machine would start. Then loose power again. I primed and get more air and it would start then same thing. Could a bad pump/ bad rubber primer pump cover cause this issue? It seems like fuel filters may have been clogged then when priming the rubber boot did not let me get all the air out? Does it sound like I am on to something?
