i just broke in a trx 2.5R engine about a week ago and it ran great when i finished the break in. when i finished the break in i tuned it just a lil bit and it ran fine for a few days up until about 2 days ago when it all went bad. the motor wouldnt idle and it ran awful. i adjusted everything and it still ran bad so i reset the carb and started over and it still wont run right. any sugestions i would really appreciate it
