    I just bought a new scag wildcat powered by a Kawasaki LC 26. It seems like it runs vary lean. If I try to engage the PTO at anything less then full throttle it kills it unless I bump the choke as I engage the pto. (LEAN MIXTURE)Is this normal for the new smog motors or do I have a problem? Has any one else had this problem?

    This is not normal for kawi motor, I run 23 kawi on my 52" Gravely, I always engage blade @ 3/4 throttle (my mech said to keep belt &pulley& pumps healthy) before running & cutting at full throttle. It never acts like what you said. All my kawi run on 10w-30 amsoil.

    I have two of those motors and they have never done that. I do have to run it about 50%-60% throttle to engage the blades, though. When the motor's fairly cold, I may have to run it a little higher but once it's warmed up, 50% throttle is a plenty.:)

    Better get that checked out, If the engine is running lean it will cause it to run at a higher than normal temperature. Does it do this after the engine has warmed up? I have a 19 hp Kaw and I warm up my engine for a few minutes then engage the clutch at about ½ throttle no problem. Call your Scag dealer ASAP. Don’t cook a new engine.

    I have the same engine on mine and have noticed the same thing. I think the owners manal says use about 3/4 throttle to engage blades. I found I can engage blades at a slower speed by giving in aboue half the choke setting.

    The engine is water cooled and the temp gauge stays centered in the green the whole time I am mowing, so I don't think it is overheating.

    I have the same motor and it does the same thing also. I just choke it to engage the blades when it's cold. When it's warm it doesn't do it as bad.
