What he said. If you can't temp the engine, use a good tach and lean until you think you aren't going to gain anymore rpm. Check the plugs after a run and look for the plugs to be a tan color. After you've done this, and the engine is warm, fly the airplane and see how it transitions in the air. You can tweak the low end a little bit if you need. On the first flight of the day next time out, as soon as you get it running, advance the throttle and see what happens. It should stumble until it warms up. After 30 seconds or so, you should have good transition.
