I have a 2001 Yamaha 100 4 stoke. Friday on the way in from fishing it started knocking. I was running at about 5500 rpm slowed down to 2000 rpm and it would stop, gave it a little gas and it would start again. While filling up Friday mourning I notice a dark stain on top of the gas tank. It looks like a water stain. Could water have got into the gas tank and caused it to knock?
If you must mount the gallows, give a jest to the crowd, a coin to the hangman, and make the drop with a smile.

Or a rod. Drain the gas, Put in some new gas, and maybe put in a little alcohol to boot to neutralize the remaining water in the system. Give er a try and see if it clears up.
