My ryobi is still in its weed wacker state, but as this will be my frist converson I would like to have it running well before converting it.
The engine starts fine but once its warmed up (after about 2mins) it starts to die and wont restart till its cooled down.
Any ideas

Cheers stu

Too lean overheating.. readjust and clean carb.

I agree it could be way lean. Also what oil ratio are you using?

It could also be an airleak.

Although the chances are slim because you have not modified it yet.

Is it stiff to turn over when it quits? Some Ryobis suffer from a crankshaft fit that is too tight in the main bearings.

LuLu: Does your Ryobi 31cc have good compression yet ....will it hand start? If not maybe its is ready for a bowman piston ring too! Capt,n.

Thanks for your replys, I cleaned and adjusted the carb and got it running really well. But after I stop the engine fuel started to drip out the carb air intake and the engine becomes flooded, but when the engine is running and i tilt it over so that it has to start sucking the fuel it starts to die.
The carb diaghram looks to be a little hardend do you think this could be my prolbem?.
It has a zama c1u carb, is it a good idear to swap to a walbor carb if so what one?

A diaghram that might be a little hard is hard enough to replace.

Yep, they need to be very flexible to work properly.
