the first day i took it out after i got it, it was acting funny. it did perfectly fine on the first job, then on the second it started to choke/bog out. its like i wasnt holding down the left lever really hard. when i got to the 3rd place it was really bad, and the motor would pop every 3 seconds or so. it got to the point where it actually cut off. i finally called BOP on the job, and they told me to tighten the cable on the lever because it sounded like there was a lot of play in the cable, like the mower was still on choke or something. so i did that, and went to the last place and it did a tad better, still would pop every now and then. well today i cut my own lawn and it choked out again, all the time. something isnt right. anyone have any problems with this?
