Engine Knocking Then Wont Turn Over

[dubranger20]

Well i got my new reeds in and it ran for a few mins then it started knocking and shut off well i took the top end off and noticed the piston rod was stuck well i used some pb blaster on it and it moved but it keeps sticking and hitting that lip what do i need to do? i think it got moisture in it could that make the thing lock up from the bottom end

OH NO! Time for new crank. Grab the crank rod any movement up in down on the needle bearing there is BAD. Im almost positive your lower needle bearing is shot. Not a cheap fix either unless u can do it yourself.
