I recently replaced my clutchbell, clutches, gear carrier, and clutch bell. I have it all back 2gether and it starts right up. But when I give 'er gas she moves a little and that's it. If I give it a lot of gas it barely moves. I u take 'er off the ground and give it gas it's normal...what could have I messed up when I was putting it back 2gether? Thanks.
