I have a 2001 Exmark Turf Tracer HP 52" w/ a FH500v Kawasaki 17 horse v-twin. The mower cold starts really hard. I actually can't get it started without a shot of starter fluid. I just dry compression tested the mower and got 130 psi on both cylinders. What is the compression range these mowers should have? Note: When the mower wouldn't start up cold I checked the linkage to the choke butterfly and it is operating correctly. I'm pretty good at fixing things. Even better at breaking things... nonetheless don't water down your answers and thanks for the help!
