Here is my problem: I finally called my Exmark dealer and ordered the Canister Air Filter upgrade for my 23 hp Kawasaki. I was previously told by this dealer, and others here at Lawnsite, that this package is now available. My dealer asked for the 'engine code' and said it was necessary info to get the correct filter. My engine code is: FH680D-AS05. This is a 23 hp horizonal-shaft air-cooled engine and is on a 2001 Lazer Z w/ 60" deck. The engine code (& serial#) is printed on a little white sticker on the engine...next to the oil drain gizmo. My dealer called this morning to tell me that Kawasaki does NOT offer a kit for this particular engine yet. Boo Hoo! Here is where I need your help: If any of you fellow members have a 23 Kaw with this canister filter upgrade would you please check your engine code for me? I want to make sure my dealer didn't talk to someone who was misinformed, or recieve a "blow-off" from his supplier just because they did not have it in stock or did not want to bother with special ordering it......this happens sometimes. My dealer, although I adore him, does not seem to get good info. I ordered the 'anti-blowout baffle' at the same time...and he said "Whats that? I've never heard of it. Do you mean the cover plate for the discharge opening?" Luckily, 65hoss has posted the Exmark part number (and the Service Bulletin #) so I was able to update him on the anti-blowout baffle situation...and get mine. Whew! Thanks, 65hoss! As this is a popular Kaw engine I have my suspicions...and I want this upgrade badly...regardless of where I obtain it from. Thanks for reading this post and any help/replies/alternatives would be greatly appreciated.
