    Ive been working on cars for awhile now. But just picked this little rig up and ran great for 3 days. Let it sit for bout an hour or so tried to start and wouldnt. Cranks over and sounds like it wants to fire bad but wont. If you give it gas itll pop right over but when you let out the gas it'll die. If you start it back up with giving gas, drive around( holdiong the brake till u get to the highway) ha and drive around for a bit it'll stay running. Then it'll only idle for a little bit till it die, fluctuation from 900rmp to 400rpm till it dies. Anyone have a clue?
    Thanks in advance

    I would start with a good tune up and go from there. Since you've no idea about maintenance records for sure do plugs, wires, air filter, fuel filter, etc.
