power loss in flight

    It didn't matter what the day was like but I do live in a hot part of the country had a 110 degree day last Christmas. 

    As strange as it sounds it happened more often on the second leg / flight, hence the return line.  

    What I did notice was that if I yawed the plane and flew crossed controls it would clear straight away

    Airbox sounded like good idea...And sounded simple   Haha

    Turns out ... insanely expensive, complex and won’t fit under my radiator.

    Tech support at RANS state no such problem ever encountered
    and it doesn’t make sense to not happen initially. 

    Today, after sitting for over a week, I drained nearly a gallon of fuel from low point drain.
    And got one carburetor bowl off to find no particulates and no water.
    Also floats floated equally well and weighed 3.2 grams. 
    Did find one vent tube had come out of bale wire and pointed down instead of slightly forward. Repositioned.
    Getting the one bowl off was so difficult, I gave up on doing the other one with bloody hands and ran out of cuss words.

    Everyone says “just remove the bowls and weigh the floats”. Those people must have smaller stronger hands than this old man and or have a more spacious engine arrangement.

    Plan is for test flight tomorrow before traffic picks up.

    Here's an short Youtube video that shows an easy way to pop the carb out and check the float bowls that also helps clear any drip try / heat shield.

    I think you have linked to a different video than the one you describe.

    That one just shows how a carb needs to be seated completely into its socket...

    Hi Tyler,

    Thanks for the heads up. I fixed it.

    You were right. Wrong video. I was just trying to demo for people that aren't sure how to pop the carb out for either a carb bowl debris check or just weigh the floats. Just to show them it isn't hard.
