`One thing it does do once its running is if i put my hand over the air cleaner hole the motor starts to really rev this normal??`
No, not normal. It means two things: 1) the idle mix is way, way too lean and 2) the idle speed setting is way, way too high.
If you block part of the air intake, apparently the mix gets better ...., ie richer.
When you said you replaced needle and seat, did you mean the float needle and seat or the needle and jets in the carb throat(s)?
Just presuming you mean the float needle, I'd go back to the float level setting, check that one by either removing the float bowl and measure or by using the way described in the manual with a piece of transparent hose.
Or the check the other possibilities for the lean mixture: false air drawn in somewhere, blocked jets etc.
