[QUOTE="ossagp, post: 197981, member: 1650"] First thing I think I would do is remove the spark plug and inspect for physical damage first. If it looks like an elf with a hammer has been in there the dropped valve that Steve is talking about sounds like a distinct possibilty. If the plug looks good other than color then you probably don't have the valve problem (though that was the first think I thought of). Ground the plug to the engine (if your friend knows nothing about motorcycles give him a screwdriver to hold the plug to the head with. if you want some real fun, give him a "screwdriver" to drink before he helps you with this test). once it is grounded turn the switch on (if so equipped) and work the kick starter. see if you have spark. If so, I would check to make sure you have fuel getting to the carburetor (take the line off with the valve in the off position, hold the hose over a fuel can and turn it on). Do that out of doors. if you have flow to the carburetor you can try putting some fuel down the spark plug hole, reinstalling the spark plug. and kicking it through. if it tries to run, you can bet that you may have a problem inside the carburetor. A condition known as "dirty". We can all take you on to the next steps, but your engine needs fuel and spark to go. Like the others I am concerned about what you have in the "locked" dept. [/QUOTE]
