My motor has been problematic from the start, and it seems to have basically the same problems as everyone else. <br /><br />I can pull a tube, but it takes a while to get up to speed. <br /><br />Skiers are touch and go, up on 2 skiis is fine just takes a while to get to speed, one ski forget about it if the skiier is over 130 pounds. <br /><br />It seems that my top speed is about 30 MPH @ 4000 RPMS, I can coax 4500 with the trim. <br /><br />I have replaced the spark plugs, played with the mixture, cleaned the carb.. I did other things, but I can't really remember what. <br /><br />Here's the wierd thing though - I can "trick" the motor into gaining speed by turning right really sharply. Does this have any significance? <br /><br />I've been getting really random performance from different props. 15 17 and 13.. they seem to work better at random.<br />Thanks a lot<br />Elia
