Just got my 1886 started the other day for the first time for me. It had been sitting for quite a few years. It seems to run great, but it does smoke quite a bit. It has the Kohler k482 in it. Is there a known problem with these engine that when they smoke like this it is usually something specific? Or is it just worn out. I let it run for about an hour, but the smoke didnt get any better. Any suggestions? I am willing to pull the engine and rebuild it? just hate to as it runs so well.
