i just finished hotrodding an avet 4/02 and here's what i did.
spool bearings opened, cleaned and lubed with corrosion x
side plate bearings packed with grease, shields re-installed
drag washers cleaned and greased with shimano drag grease
screw holes greased with yamaha engine grease
4/0 handle replaced with a 5/0 handle
drag plate shimmed
this reel now delivers 30#'s of drag at strike before losing freespool, only a slight amount of load when cranking at that strike setting, and 45 seconds of freespool also at that strike setting. this means that the avet 4/02 will no longer have to languish at a max drag setting of 17 pounds at strike before losing freespool. it can FINALLY fish shoulder to shoulder with the penn 30s, the tiagra and accurate. we're talking 100# spectra and an 80# topshot with 30#'s of drag at strike.
