this motor is on a 52 scag. i think it's 2009. the motor has less than 300hrs. my problem is the motor runs fine 97% of the time but it sounds like it drops a cylinder. when it drops a cylinder it runs rough and the exhaust smells like fuel or (rich) then it will start running good again nice and smooth. would this be a coild going bad? also the last few days it's been hard to start on the first crank up of the day. after it finally starts it cranks and starts fine.

Might be a coil going bad or something as simple as loose or corroded connections on the coils.
