There's nothing unusual about that. It's impossible to overlean on the ground, so there's basically no reason not to pull the red knob to just short of killing the engine. I lean -- a lot -- after start and immediately after I land, when I'm turning off landing light, retracting the flaps, etc. A side benefit of leaning aggressively on the ground is that you'll never be able to accidentally take off that way. Your mixture knob should be far enough out that if you advance the throttle to full, the engine will stumble. That prevents you from forgetting and taking off with the mixture too lean. Can't speak to whether you have a bad batch of fuel or not, but there is nothing at all unusual about needing to lean on the ground. Every Tiger I have flown will get fouled plugs almost immediately if you don't.
