I have a YS 45 FS that my father had and im having problems with the carb flooding out while trying to start the engine. I have searched trying to find a operators manual for this engine with no luck. Im new to setting up airplanes and trouble shooting so any advice will be appreciated.. im also new to pressurized fuel systems like this engine has .. Its does have a check valve in line to create the pressure but i believe the carb needs to be cleaned with gaskets replaced.. i just need advice how to get a manual or parts list for the engine..
Thanks
