Ok so I just bought a Husqvarna LR 100 used and it hasn't been ran in 10 years are so but it was winterized before it got put away. Everything is mint on it the motor looks like it's a year old or so but it needed a new battery so I got that changed the plug tried firing it up fo the first time in 10 or so years. Turns over fine didn't start so I took the bowl off the carb and it was pretty gross I cleaned it all out and sprayed the float and most of the parts inside the carb but I didn't take the whole carb off. But anyway tried firing it up again still didn't start then I sprayed some carb cleaner in the top of the carb where the airfilter goes and it started for a second then just died and it won't start at all and can't figure out why. Should I clean the air filter? Change oil? I'm not to sure I'm new to riding mowers so if anybody could help me that would be great thanks.
