I have a 1998 Yamaha F50TLRW that idles great but will not run faster that 1/4 throttle under a load. Here are some things I did and found. I took some bad advise and stored it without running the gas out of carbs. I was told if it had the Yamaha Ring Free additive in it you did not need to run the fuel out of the carbs when you store it. I bought more Ring Free and shocked it. I read on the bottle that it is a good idea to change the oil after the shock treatment. Today I was going to change the oil and I check the level and it is up to the top of the dip stick. The box that hold the incoming fuel line and the line to the filter has oil in it, should it? I drained my fuel tank and cleaned it real good. I cleaned the filter and put in new spark plugs and it still will only run about 1/4 throttle. Could oil be getting into the fuel somehow? If there is not something that you guys can think of, I will take it in and have the carbs gone over. I just wanted to eliminate all possibilities first. Thanks everyone. Larry
