Help guys! I just finished my U Can Do and took it out for the maiden flight today. This is my first go at an inverted engine. It is a Supertigre 90 that has had about 40 ounces of 15% Coolpower ran thru it. I first tried it with a Perry Pump and it was fine on the stand but when on the plane it just kept loading up and flooding the plug. I bypassed the pump and tried it again a little better but it would go dead on the taxi out. Then I turned the plane upside down and got the high and low needles set and managed to get it airborne, made 1 trim pass and it went dead again. I just gave up for the day. No need to mess up a new bird over something like this. Any info appreciated. I am going to take the carb off and clean it good it may have some fiberglass dust in it from the cowl fitting?
