Lazer Z XS - 60" with Vanguard 31 HP - only 30 hours on machine Tonight I mow the grass and park the machine on the drive while I weed-eat. I come back about 1 hour later to move it into the garage and here's what I get: 1. It won't start in its normally very easy fashion. 2. I try different combos of throttle and choke and finally get it to kick off, but it's struggling. It'll run for a moment with about 1/2 throttle and 1/2 choke. Shutting off choke kills the mower. Reducing throttle kills the mower. Increasing throttle works a little and then also kills the mower. It's billowing HUGE amounts of smoke. Although it was near dark, it appears to be "rich" smoke (rightfully so). Both tanks have gas, and she was running 100% prior to parking. When I view the linkages for the throttle and choke, it looks like hardly nothing happens with the throttle from about 0 to 1/2 throttle. Is that right? What the heck happened? Ideas? Did something fall off and allowed it to run until I parked it and now it's whacked? Thanks!
