you will have to remove on of the side panels. although i cant remember of the top of my head which side has better access. anyway, pull the side panels off, and then if you have the OEM spark plug wrench that came with your machine, use that, it works pretty well. pull the spark plug wire off of the spark plug. WORD OF CAUTION!!!!!!!!!!! i would absolutly take a fine tipped air compressor nozzle and blast a buch of air in the hole the spark plug is in after you have removed the plug wire. you want to blow any and all dirt that is in that hole out of there. you do not want that to fall in after the plug is removed and have it take out your piston rings.
put the plug wrench on the plug, and untread it just like a bolt. put the new plug in, screw it into the motor, (start it by hand first and get a couple threads going before using the wrech so you dont mess up the threads) push the spark plug wire back over the top of the plug, should feel a little "pop" once it is seated right over the plug, and see if it fires up better.....
if not, its only a $2 plug and 15-30mins of your time. start with the simple easy cheap possibilities first and ill help you work up from there. let me know if a new plug helps at all
