Looks lilke this is going to be a fine little engine. Cranked right up this morning with the first tap of the starter. Didn't even have to adjust the needles on a Bambula 18x8 which it turned at 8400rpm with the stock muffler. I know that's kind of a small prop, but I wanted to go easy on the motor until I get a couple of tanks through it. I did have to richen it up a little with a Pro Zinger 20x8. Looks like the Ultra Stik is fixing to get a major horsepower increase!
