Hey everybody, I've got a 455 rancher that runs and cuts fine but when it's warmed up it will idle for 10 secs or so then rpm's start climbing (like it's running out of fuel) then it dies. I put a new carb kit in it since the diaphragm was a little stiff but not to terribly bad, but still same problem. I put a new fuel line on thinking it had a pin hole in it somewhere but still same problem. So I started thinking this is an air problem vs fuel problem. I've checked all gaskets and mating surfaces even made a couple gaskets to got in between the filter holder and the carb. I've even sprayed a little starting fluid around all mating points, the motor does die but it acts like it floods it out. I'm stumped on this one. Any and all help is greatly appreciated.
