Hello everyone I'm hoping i can get some help. I have a 1999 J25REEB 25 hp Johnson that i replaced the power pack 113-4767, charge coil 173-1670, sensor 133-3387 as well as the spark plugs ql77jc4 and spark plug wires. when i installed the parts and tested the spark jump it was really good. ran the engine and ran well . shut the engine off and adjusted the carb as idle was to low restarted the engine and noticed it wouldn't idle very well. checked spark one more time and only one cylinder is firing . the bk/ylw wire is disconnected and still no spark on one cylinder.
