I need some help. I have a Fountain with twin 502's. These engines are reworked with fuel injected B&M 250 Blowers. The starboard engine runs great very little blower surge and idles around 7-800....I can live with that, the port engine idles at 1200-1300 and has alot of blower surge anything under that. Any ideas????
sounds lean like you have a vacuum leak somewhere.
