[chester12887]

Hey guys as stated I've got a 2007 cub cadet rzt 50. The handle bars are all the way out the seat is pressed down pt9 is off and brake is on. Turn the key the starter spins the motor but won't start but after a few tries to start it it back fires.. I've checked to make sure its getting fuel carb is clean and getting fuel. I've done a compression test on each cylinder. Again 110 psi in each cylinder where it needs to be. The oil is good its getting spark. When my wife used it the other day the fuse blew. I replaced it no biggy near the end of last season it started to get a little hard to start and would randomly cut out. And its Been like that all this season. I just put all new tires on it and i dont wanna get rid of it somebody help me out it driving me crazy..

Replace spark plugs, fuel and air filters. Inspect all wiring, wire harness plugs and connections for chafing, insulation missing and being tight. Let us know if you get it going, if not, post model number as well as all numbers from engine.
