I bought a smartdrive Honda from Home Depot this spring for small yards. I've had problems with it all season, and then oil started leaking out of the airfilter yesterday. Since this was happening I decided to try and start and up another Honda mower that was given to me by one of my customers this spring. It's a real nice mower in good shape but has sat for 3 years or so. I've changed the spark plug, oil, put in fresh fuel (there was no fuel in it when I got it obviously). I took off the carb and soaked it in carb cleaner. It starts after several pulls and then dies almost immediately. Anything else I should try or that you could suggest? It would be a great mower if I could just get it running. Thank you. I don't know the exact model number, but it's not a harmony and I think it's a little older than these new smart drive setups.
