the cloud of smoke indicates a really rich setting---so do your high EGT's---you're getting unburned gasoline in the exhaust runners by the probe---of course it could also be hella lean so dont' quote me on that, but thats my guess--you really do need a logger*EDIT* and by "unburned gasoline" i mean the combustion process is continuing into your exhaust manifold...hence the high EGTBut like I said, lean this out at your own risk---I wouldn't, its just my guess, and i have been on my feet all day after 2 hours of sleep
