been having trouble with flooding after engine is shut down. i was firing engine in my house before driving. idled fine and engine was responsive to small inputs of throttle, so i thought i was good to go. but when i went to start it an hour later it was majorly flooded. the cylinder was almost full of fuel. dried it out and had it running again and the same thing happened. thanks for putting up with the newbie...

How are you stopping the engine ? You should pinch the fuel line till it stops.. You may also be a little rich on the HSN (high speed needle ) When the engine runs do you get fuel splutter out the exhaust ?

ok i am a real newbie at this i bought a car from a kid and he messed up the carb settings and i know nothing about it and some one help me with the setings on an os max .21???
thanks the newbie

Try www.osengines.com and look for a manual on their .21 engine. My guess is that it is 2 1/2 turns out from closed on the high speed needle, which is the one sticking straight up off of the carb. The low speed needle should be flush with it's outer housing. It is located on the other end of the carb. It is in the center of the carb linkage connection. These settings are break-in settings, but will be safe to get the engine started with. If you are having flooding problems, turn the high speed needle clockwise to close off the available fuel flow.

One thing that has really helped me, since I am also a newbie, is to think of the high speed and low speed needles as the valves on a garden hose. The high speed needle turns the flow on to the garden hose. The low speed needle adjusts the amount of water coming out of the garden hose.

but i have a problem with finding a manual for that motor is disscontioned and i can not find one there but i might have a copy of it coming
but thanks for the info
