OBSERVATIONs at the field of how well others' engines run are not as telling as you think.

One of the last few times I went out to the field, I dead-sticked twice in a row. If you don't know any better, you'll take one look at the engine brandname and say: "don't mess with those XXX's, they are a POS. Get an OS next time." In reality, the first deadstick was caused by the high speed needle being too lean for the conditions that day. When I dialed it in correctly the second time, I was having so much fun I ran out of fuel!

MDS had its share of troubles, but the new carbs are doing quite well. I would not hesitate to try one, especially given the excellent service Horizon gives to this engine line.
