Hello I am new to this forum so please bear with me: I have a 1992 Galaxy W/A with a 4.3L(262) V6 with the Thunderbolt ignition, it has a carb, the engine is about 5 years old, last summer I was having problem with the thing popping and cutting off, which ended my fishing season early, so this past spring I went ahead and replaced the following parts: Cap, Rotor, sensor wheel, wires, plugs, fuel filter, water separator, oil changed, it ran great until the end of July, the family was going out of town so It was filled up at before we left, it sat on the trailer for three weeks before it got used again, I went down to put it in the water and noticed that the vent for the tank was broken off inside the boat, also noticed that I hadn't hooked up my second battery ( hooked up) and replaced vent and fuel fill. Put boat in water noticed it seemed like it had a rough idle, we out to clear it out and it made it to 2800 rpm's and started sputtering and popping, figure great what the hell happened. went back to the dock unhooked second battery figuring it was causing it. Went out next day with the family for some beach fun and it popped and we idle to the beach area. it would run ok up to 2000 rpm's. Talked to several people they said check you coil, ( put another coil on it- one I had) it ran worse, put old coil back on, also was told replace ignition switch it is always over looked, replaced ran better, but still sputtering, adjust carb no change, pulled fuel separator and drained no water, replaced with new and replaced fuel filter, pulled cap not moister and wires are good. I want to be able to go striper fishing this fall, can anyone help me with this, I plan on getting a new sensor for the distributor this week. Please help.
