so i bought another blaster yesterday and did a compression test had 70psi after 5 kicks kickstart was hard to kick but does move. so i figured rings a seized so i took the topend apart today and piston rings and sleeve look great the piston was sitting in the bottom so i went to pull it up to look at the rod and crank and it wouldnt move. i got it to come up by pushin the kickstart down. it doesnt move up and down by hand like my other blasters does so my question is does that sound like a rod bearing? and how hard is that to fix and how do i go about fixing it?
