Question about Craftsman 42 in. Deck 19.5hp Lawn Tractor
I have a 42" 19HP craftsman riding mower that requires the choke to be pulled out to run. I have changed the in-line fuel filter, removed the carberator bowl and cleaned it, replaced the air filter & pre-filter, blew out the fuel lines, drained the fuel tank and used fresh fuel. It runs great for a little bit( 10-15 min), then seems to load up and require more choke to keep it running.
Oftentimes, this problem is the result of mowers left outside in ambient air that is high humidity. This, in turn, allows algae to grow inside the carb fuel float bowl and/or inside the fuel tank if left out for extended periods (one month or longer). Also the same thing will cause air filters to clog rapidly with mold and mildew - slowly at first, then more rapidly as the mold continues to grow. Get out the carb cleaner in spray cans and go through every ported passagewway in the carb body then reassemble using CLEAN screws, gaskets and all interrior parts. Any residue mold or mildew will continue to grow - and it can grow in gasoline!! Imagine that!!

It still sounds as though there is a passage plugged in the carb or maybe a leaking gasket. The carb is obviously not pulling gas through as designed, which explains the need for choke. Try a rebuild kit, and blow carb cleaner through every tiny passage.
