Hello I just purchased this boat and first trip out to the lake I tried to full throttle and found out that the boat was only running 2500 or so rpms. I brought the boat home and checked the cylinders. Compression is good on all 3, spark is good on all 3 as well. The second cylinder is dead not combusting, plug is always wet and black I have taken the carb off and it has been rebuilt and cleaned and still having the same issue. Not sure if this is a timing issue or what but it is very frustrating. If anyone has any ideas it would be appreciated, I just ordered the manual but thought maybe someone might know what it was first. Spark advance says 17 degrees, I hooked a timing gun up and with it WOT it is at 17 degrees and when the throttle is at idle the timing is nowhere near the timing marks period. If anyone may know what the issue is it would be greatly appreciated.
