Kevin--- We have the same TOL mower, except mine is now 3 years old and doesn't have the cupholder (damn!). Mine has been very reliable and as long as you don't turn the mower on its left side (allowing oil to get into the air filter/muffler) you shouldn't have any problems.
I used to turn my old mower on its side to spray off any accumulated grass gunk underneath the deck; did the same with my new Snapper and found it started to run roughly, was hard to start (even with the electric ignition) and would stall in areas of tall, thick grass. Oil was getting into the filter. Now I just tip it up at a 45-degree angle and spray it out. No problems!
