Well i got my 88 cc kit in from dr atv, heavy duty valve springs and race cam. Im not sure if my plug is fouled or the timing is off. Its not any faster that before with a worn out piston. Do i line the timing mark on the flywheel "F" or the "T"? to the notch on the engine? I lined it up to the "T" and i have the cam sprocket circle lined up to the notch on the head. Is that right? Or am i supposed to use the F? Thanks

Sounds like you have the valve timing right -("T" on the flywheel & "o" on the sprocket.)-What about ignition timing "F" on the flywheel & points gap?

You set the valve timing up on the "T".

You set the valve timing up on the "T".

Check your ignition timing. If your timing is out of whack, you won't be making power. Set the point gap using a light bulb and the "F" mark.
