1st chopper blues-need ya help guys,BADD

This is my first chopper and i have no idea what i'm working with except its a 2 stroke. Don't know if its a 47 or 49cc, but since it looks nothin like my pocket engine i have 2 assume its a 49. Also the carb (i know the pic shows it from the bottom) is this a hp carb? I removed it-cleaned it down and put it back on. Bike started up and ran, but then it bogged out and doesn't want 2 start back up. It has once but since then nothin-and i think the spark plug may get flooded, and thats why! But not sure. Also the clutch housing has a screw at the top of it and another on the bottom, when i mistakingly took out the bottom screw-oil poured everywhere. I know i have 2 replace it-but how much and what kind and what is it 4? Final question- does anybody know what kind of chopper this is? Thanks 4 the help peeps ~K

I have this exact same bike but in a salvage state as it was given to me to fix and keep. Mine is a 49cc best I can tell.

That's either a 43cc or 49cc motor. The carb is just the stock carb and you can try to reset it to 2 1/2 turns out. The mixture screw is the brass colored straight headed screw on the side. Turn it to the right softly until it stops than turn it 2 1/2 turns to the left. When you cleaned the carb did you clean the tank and fuel lines also? The oil in the tranny can be motor oil or gear oil it don't matter which. Thats the gear reduction box and it needs oil in it for the gears that are inside it.

Thanks alot Dawg and 99- gonna try what u said and no i didn't clean the fuel lines out, can u please advise the best way 2 do that.

Just spray some carb cleaner through them or replace them. I just got 1 of this choppers to but the motor in them is nothing new to me I.ve been messing with them for awhile. I just wish there was a good pipe for them.
