When I cleaned the carbon off the pistons, heads,etc., I cleaned the valve stems too and they were not tight in the guides. This was done about 50hrs. ago.
Fuel is fresh at each cutting, at worst a week old.
Sometimes a puff of black smoke and the smell of running rich when it stumbles.
I wouldn't say a large cloud of black smoke.
