weird noise
 
i just fired up my alpha .60 a while ago for the first time and it was a little rough. the first time i started it it idled really rough and when ever i tries to rev it up it would start to die and it would make a clicking noise. it eventually started to run good but after i tried to start it again the same thing happened again. is this normal? and is a lot of oil in coming out of exaust normal? i know there should be some but at about half throttle it pretty much pours out.

without being there it sounds like it is running very rich. that is not a bad thing for a brand new motor on it's first run. the clicking I am assuming is after you run it and turning the prop by hand? If so that could be normal on a new engine as well. the best advice I can give you is to get with your instructor before you go any further.

What type of engine is it?

could that clicking sound possibly be the piston pinching the sleeve and pushing it up and down inside of the motor

Is the engine a four stroke? There was a thread similar to this a while back.

the engine is a evolution .61nt. and the clicking noise is only when i rev it up and then it starts to die. and when idle it sounds kinda sad. It may be running rich but it sometimes runs fine without any problems that i can see. the oil may be because it is running rich but i don't know much.
