Hard to imagine it was lean as it kept quitting on the bench until I leaned it out. I didn't put it back up after leaning the low speed, due to the transitions being off, so will give it ago next time out using the 32:1 that is for it. Just have to remember to put it in the truck. At least this time I used a half tank of fuel, so had a good long flight, I usually land with 3/4 tank still. I got about 20 minutes of flying in.
