I have a H-9 CAP 232 powered by a Thunder Tiger 120 (2-cycle). I use the dot system with the tee fitted on the fuel supply line to the Cari. I have throttle kill set up on my radio which closes the throttle all the way. I have never flooded the engine and it has worked fine. Just remember to verify that the throttle is closed before fueling. That's a mistake you will only make once.
