Hi guys, just took my ts2 down to the local pond to fine tune it. I have the O.S. .21 xm, and I am fairly sure I broke the engine in properly ( slobbering rich, good smoke trail, fuel flying out of the carb, etc.). I broke the boat in out of the water ( used a water pump to cool it, and kept it from revving all the way), for about 3 tanks. So I had the high speed needle at two and a half turns out, and the low speed at factory setting. The boat would hardly idle without dying ( seemed too rich at idle). So I leaned it out a touch. I tuned the engine by ear to scream out of the water, but when I put it in the water it seems like the boat is not getting up to speed. No cavitation here, im talking serious bogging down. Ive tried leaning both needles a touch, one at a time, etc, and no results. Im at wits end here. Ive had no problem tuning nitro engines before, so im a bit baffled. Motor has literally no power in the water, but revs and idles nicely out of the water. If you guys could give me some good starting points for the two needles, this might help. They are a bit vague on the low speed setting in the manual. Ive ruled out fuel delivery issues by rerouting the fuel lines cleanly. Ever since I bought this motor ( before it was even fired), it has had a real tight spot in the stroke, and it almost feels like something binds. Is this normal for the O.S. .21? HELP GUYS< I GOT THE NEED FOR SPEED!!!!!
