Hello guys I was reading some other threads and no dice I have a 2000 Polaris trail blazer 250 the guy I bought it from had said it sat for a year and of course its not running so the first thing I did was test spark checkmate it had a nice blue spark I cleaned out the old gas from the tank cleaned the carb it turns over but won’t start so I tried taking the carb out of the engine intake and pull start it to remove the gas this time I pulled it it felt like it started for a sec but then nothing then I tried once more and it backfired so anyone got aNY ideas anything would help
