14/17 seems a bit tall... what engine are you running?..... I have 11/14 in my ff with proline maxx wheels and I can barely hit 2nd with the os 18.... try gearing down the clutch bell to 11/14... the engine probably can't pull the tall tires and the high gearing... That would explain the bogging... Before I fixed my shift points, mine would start in 2nd with a bad bog...
