[QUOTE="Rich Rohrich, post: 1346793, member: 16241"] A two-stroke plug should NEVER look wet if the plug is the correct heat range and the jetting is correct. If the plug looks wet you have a problem that needs to be corrected. This is what a two-stroke plug should look like : [IMG]http://www.dirtrider.net/gallery/files/1/6/2/4/1/16241-Justaboutperfect.jpg[/IMG] This is a plug with nearly perfect jetting. The fuel is Phillips B35 unleaded, oil is Phillips Xamax mixed at [b]18:1 ratio[/b]. It came out of a 150cc MX bike ridden on a tight track by a really slow guy ( ME :whoa: ) . Even with a lot of oil in the mix the plug should be clean looking if it's running at the right temperature. If a plug looks wet it's running too cold, and will tend to foul or at least misfire under load, which is much more difficult to track down. Two-strokes that are used for slower speed trail riding usually need fairly lean jetting on the pilot and needle along with hotter plugs, compared to the factory "safe" settings they come with. The plug is an excellent indicator of how well the engine is performing, and if it's wet you are leaving a lot of throttle response and power on the table. [/QUOTE]
