I recently took my summit apart to try out some different gears.  after putting it back together it work fine for a little bit but then the spool quit turning when turning the handle.  i think that problem is fixed but now there is hardly any drag tension.  what could be the problem all the parts are on it and in the right place.  could it be the drag washers turned wrong?

Check your schematic carefully and be sure there are no spacers missing. Check the spring washers and make sure they are oriented: ()

Sounds like its time for some professional intervention.

I am certainly no expert but maybe the drag star is not threaded on correctly, or something is missing/placed wrong in the drive shaft or drag stack. Either of those could lead to the spool not turning very fast, maybe not even at all. I would guess it is more likely something to do with the pinion gear and the two springs right next to it. Here's a tip if you ever decide to take apart another reel that helped me out alot: video tape the disassembly. Get some good close ups and narrate it to yourself step-by-step.
