OK - so my wife's bike won't start. It's a relatively low mileage bike that has been run fairly sedately. 1 cylinder, 4 stroke, carburated and air cooled. I'm pretty sure the battery is dead, but it has a kick starter as well, so I assume I don't really need the battery. When I try to kick start it or bump start it, there is no sign of ignition. I pulled the plug and it smells like fuel and is wet. I don't think it's oil, pretty sure it is wet with fuel and the blackness is from it being sooty. I looked inside where the spark plug goes with a filament light and it looks like the bike is running rich (but I couldn't really get a great look). I cleaned up the spark plug and tested for a spark. It sparks.... put it back in and nothing. Pull the spark plug out after a few more kick start attempts and it's wet and sooty again. I took the plug out, and with the plug out kicked the bike slowly a couple of times to air out the cylinder and kept the spark plug out for a little while. Tried again a bit later and no dice. Spark plug was sooty/wet and smelled of gas.
Bike was put away and hasn't been used in about 1 year..... pretty sure I put fuel stabilizer in the bike. It seemed to be running fine when I put the bike away. I checked the air filter and it's nice and clean.
Not sure where to go from here. Suggestions?
- I can try to siphon the fuel out and try newer fuel, clean out the carb and see if anything seems odd in there...
