Don M,

I can see why you're frustrated when it comes to gas engines.[>:] The only time I've seen that much oil come out of a gasser is when it's either being broke in, or the needles are set too rich. I can fly my DA50 with stock muffler or G62 with B&B muffler at 50:1 for 7-15 minute flights, and just have a few spots of oil on the side of fuselage and tail feathers. I do get some straight oil on the wing from the carb on the G62 plane, but all this wipes off with just a dry blue shop towel. I just got done breaking in the G62, and it did put out the black crap for 2 1/2 gallons, now it's just unburned oil.....
