i got a husqvarna hu600l about 2 moths ago i was so excited and then i added fuel and oil the night before and then the next day the mower wouldnt start. so i returned it to sears and they gave me a replacement this time it had a 173 cc engine but i added the fuel and the oil and the next day it wouldnt start PLEASE HELP ME IF THIS ONE DOESNT GET WORKING ILL BE FORCED TO BUY A CRAFTSMAN!! ps: both of the models do not have a primer. this has a kohler xt-7 engine with 173 cc
