Bought kit as combo w/ a S.T. .51 engine. Mounted motor and it is crooked by about the amount the plans said to cut off one side of the fush. Also had to cut off the back of the cowel to get the prop plate out far enough. Now the carb is jambed up pretty far into the front of the cowel. It also doen't have a rear mount needle valve and that is going to look funny with it that far up. Haven't cut any holes in cowel yet any sugestions? Do they make a long shaft motor and can you get a rear mount needle valve add on kit for Super Tiger?
