    Problem: wont start think its a Carb related issue
    and has a flooding issue when i leave the gas on it floods the top end of engine to the point where gas is
    comeing out of the muffler not sure on exact carb adjustments
    if anyone know how to get back to factory settings let me know

    Attempted solutions:
    Cleaned carb
    Cleaned coil+Fly wheel for better spark
    replaced spark plug cj8

    any other suggestions?

    Replacing the float needle valve should solve the flooding issue.

    Need the engine spec number to go any further.....

    the best i can do is fb460v GSD5 or GS05 cant make it out if its D or 0 zero
    then for serial # xH150 x65500 (the x's represent numbers or letters i cant make out)

    Close the low speed adjuster lightly then re-open 1 1/2 turns, This is a starting point for start up. Once the engine is warmed a bit set the throttle to idle then adjust the low speed to the smoothest idle. The high speed is non-adjustable.
