I have a 77, but there's a decompression lever as well as a clutch (they are both black, under the brake levers), you need to pull on both of them while you are kick starting. Also make sure the petcock is turned straight up, so the gas is flowing and the kill switch (the round silver thing) is set to "run". Mine also has a plate with the vin number/year on the gas tank near the seat where you can find the year and what not...
Also, if you do a search in each of the forums you can find a lot of information about these bikes.
Good luck. i love mine, i hope you like yours too.
