J/30 Class Association Forums J/30 Forum The Boat, Sails and Equipment Engine Trouble

Thanks bill, used kerosene to clean out the tank as best I could, definitely some sludge in the bottom. Replaced fuel filter and bled all lines to the injectors. With some persuasion I can get the engine to fire but I can't get the forward cylinder to fire consistently/evenly. The rear is steady and smooth but the forward is louder and more metallic sounding and will miss when the throttle is pushed and won't run at all at idle. Come to think about it, the engine has always had the loud tinny sound from I'm hearing from the front cylinder, I just assumed that's the way the engine sounded and you j30 guys were just gluttons for noise abuse but now that it's missing I can hear the rear cylinder firing on it's own and it's much smoother and quieter. Now I'm thinking injector? What's involved in replacing/tuning? Hope this thread helps someone else struggling with their engine.
