Hey, im new here and i need your help. I just bought a 96 zrt and before i bought it i drove it and it had a bog but i didnt figure it was a problem since it hadnt been ran in 2 years. I figured it needed the carbs cleaned. But i was wrong ive cleaned the carbs and Jetted them, new fuel filter and the same problem. when you press the thortle it bogs for a couple seconds then all the sudden runs great until you let off the throttle and press it again and you have the same problem. Help me please.
