last night it worked decently while i mowed the front yard, but starting losing power (like if you got into some really high grass and it was a little much for the mower). when i got to the back it just stopped. it would crank when i pulled the cord, but would then quit. the other day i didn't realize it was out of gas, so i was trying to crank it for about 10 minutes before i figured it out. could that have clogged something up?...the Honda engine doesn't have a primer, u just open and close the fuel line. fuel filter, maybe something else? by the way, any suggestions on where the fuel filter is on 21" Troy-Bilt push mowers in general?...something easy to access?
