I have a Husqvarna YTH1842 tractor mower. When I was mowing the other day I stopped for five minutes, then it wouldn't start. There was a lot of back fire. I changed the spark plug and the fuel filter, but that didn't help. Before the season I changed the oil for the first time. When changing the plug I think a little fuel (or carb cleaner) came out. I took off the air filter and sprayed carb cleaner in there and started a small fire. Please help.
Check your fuel. Mowers weren't meant to run on fuels with ethanol and it's starting to cause problems in cars and small engines (especially in areas where unscrupulous fuel companies are adding more than 10% to the mix). If your fuel is left over from last year the ethanol might have attracted water into the mix. (Just so you know, the "water out" products that they sell at the auto parts store are isopropyl alcohol and nothing more.)
Aside from that, let us know what happens when you turn the key. Is it turning over and trying to start or simply doing nothing?

Request: Husqvarna Riding Mower Won't Start (06/19/2009)
My 2002 Husqvarna riding mower won't start or roll freely. It is a YTH1746 with Kohler CV490S Crown Series engine. It got harder to start over the last month, I'd charge the battery and it would go. Then it quit starting at all. I replaced the starter. No help. I replaced the ignition switch. No help.

Request: Husqvarna Riding Mower Won't Start

My 2002 Husqvarna riding mower won't start or roll freely. It is a YTH1746 with Kohler CV490S Crown Series engine. It got harder to start over the last month, I'd charge the battery and it would go. Then it quit starting at all. I replaced the starter. No help. I replaced the ignition switch. No help. I ran a jumper from the battery to the starter, and the starter would spin and turn the engine, but there was no spark that way for the engine to start. If it were a fuse, it wouldn't have failed gradually.
I have no manual and don't want to start tearing it apart without some better idea of what I'm doing. Maybe it's the spark plug, but I'll have to start unscrewing things to find that. When it ran, it ran fine. Also, when I pull the lever on the back so I can push it the transmission is still locked. I can rock it a little, but that is all. What do I try next? I couldn't even get it in the truck to haul to the shop now.

Sounds like the problem we had with our riding mower and it was the spark plug. (08/15/2008)

Sounds like the solenoid switch. That is why you can jump it from they battery to the starter and it'll work. The solenoid cost under $15.00 (08/18/2008)

First I would take off the drive belt. It is very simple to do, that would let you know if its the motor or tranny. If it moves its the motor or electric clutch if it doesn't it's the tranny. I hear the tranny is way expensive. Hope this helps. Jim (06/07/2009)
