Hello all,
I joined the group to see if I could tap into the knowledge base and see if anyone had an idea what could resolve my current dilema. I looked back about 12 pages or so in the history and didn't see a problem exactly like mine so I figured I'd post about it.
Basically the short of it is my mower (Cub Cadet LT1045), ran out of gas last season and stopped running. Not thinking any thing of it I put gas in it and it wouldn't start or crank. Since it was the end of the season i said forget it i'll deal with it next season and pushed it into storage were it sat until this season. When I came out to investigate I discovered it wouldn't crank because I blew a fuze, I replaced it and then discovered my starter relay was bad, replaced that then found the starter to be bad.... You see where this is going. So once I finally got the motor to where it would crank I found it wouldn't fire over no matter how much I tried, not even on starter fluid. I have rebuilt the carburetor, cleaned it with polish and carb cleaner, blow all passages air ways etc with compressed air (all blows freely), polished the needle and seat, cleaned fuel shut off solenoid (you can hear it pop or snap when the 12v is hit or taken away from. It), tested the fuel pump, I have spark when the plug is removed, new plug, plug is gapped to .030, valve lash is set to .005 for intake and .007 for exhaust, i just replaced the woodruff key on my flywheel, new starter, new regulator/relay, new battery, new pto switch and relay, new fuel lines, new fuel filter, fresh gas, new oil filter and oil, new air filter and sponge.
The problem is that the motor will not fire. If I play with the choke and throttle it will backfire, or fire once then torque the whole lawn mower and stop immediatly. The choke control and throttle control does control the butterfly's on the carb so the linkage is good. Motor will also bind like the valves are out of alignment even though they are in spec. I can live with the rough starts but I'm at a loss for why it won't even start/fire.
Any one have any ideas? My grass is currently about 3-4 feet tall And I really need to get it takes back again.
Thanks,
