I have a problem with my left engine on my 1966 Pa-30B. The fuel flow is noticeably higher on the left engine than the right engine at all power settings and gets progressively greater at higher settings. The engine intermittently runs rough/stumbles a few times than recovers to almost normal power. I had my A&P clean the fuel injectors (stock) and this helped for about 5 minutes but then it went back to the same symptoms. Has anybody had a similar circumstance with their aircraft? I am thinking of sending the fuel servo for overhaul. I did replace the fuel gauge with a new gauge. Thanks for any help!
