I've got a air cooled, Kawasaki FH500V, 494cc, 17HP VTwin OHV LX277.
Since last year, I've been fighting this machine as it stumbles and surges. After a few posts on this forum back then, I changed out most items usually suggested on this forum regarding "surging" problems at one time or another ... and even had some temporary relief - but always returns back to its erratic behavior. (replaced fuel pump, fuel lines, solenoid - pulled gas tank to check for obstructions) I'm convinced this is an air/fuel issue since choking the machine usually smooths out the engine at lower throttle.
I used this machine this year so far,usually being able to run at half throttle. However, running at half throttle does not allow for the best mowing job.
Question: What should I look for now when I sense this problem really takes hold whenever the mower gets hot. In other words, I use it for a half hour or so, but then it starts acting up and then gets to a point where "choking" it barely gets me back to the shed.
Advice welcome. Thanks.
