Hi all have a problem with my lt80 it was lying up for a week and when I went to start it , it wouldnt turn over cut long story short turned out crankcase was flooded so took top end apart empty the gas from it put it back together now it starts and runs but now has real loud grinding sound when its running also forgot to mention the crank wouldnt turn think it seized had to force it to rotate a few times until it became easy to move , what use think new crank bearings ?
