Im just looking for some help here guys i was mowing today in about 90 degree weather and the grass i was cutting was relatively high and i was cutting at full speed so the kawi 23hp was really getting a work out. then after about an hour(big property) i was just finishing up when my rpms started going up and down and i had a total loss of power so of course I shut her down and she looked to be hot but idk if it was overheated i mean it didn't look to much hotter than normal. so I finished up with another mower and let this one sit. When I got around to to looking at it, it seemed ok but not too much gas(still enough to work I think) so I started it back up and it ran for a bit then the rpms started going up and down and again loss of power.....this was a bout 30 mins after the initial problem....so I waited to the end of the day started it up after putting new gas in it and it ran fine. was my engine overheated or was this some sort of gas problem..maybe a clogged filter? it appeared I had plenty when I started loosing power. any ideas????
