Hey everyone, I recently got a used pony 42" with a B&S 17.5 hp and 8 spd trans. Everything worked well for a few weeks and then it would start shuttering when i would engage the blades and eventually cause the engine to bog down. I have replaced the fuel filter and checked all the wiring connections. More recently i have noticed that it will do it now even with out the blades engaged...it just starts sputtering, like its not getting enough fuel to stay running...the only thing i can do to keep it from stalling is if i turn the rpms down the where its barley got any throttle let it idle there for a bit and then turn it back up, but eventually that dosent even work. Any ideas?
