New oil leak

[GTSRider]

Now that I have engine running decent with a new Keihin carb...
and new front pto end crank seal... I noticed oil running down right cylinder,
as sitting on tractor. I'm thinking leaky head gasket..... compression test showed 180 on left ...160 on right.... is it much to change a head gasket on these Kohler engines ?
Thanks.

Have pretty much confirmed head gasket is bad.... there is a bad leaky exhaust sound...which I thought was exhaust system... but the sound is coming right from right cylinder head gasket area...
anyone changed head gaskets on Kohler V-twin ?
I don't imagine it is very difficult... I rebuild old Brit motorcycle engines as a hobby...so gotta be simpler than them by a long shot.

I think I posted a link to download the service manual for your engine in one of your other threads but if not you can go here Kohler Engines: Owners and Service Manuals: Manuals and Maintenance and download it from Kohler.
