Skylark replaced starter having issues!!

Hey guys, have a 93 buick skylark custom with a 3.3 litre. Replaced the starter last night. The starter seems to work fine (AutoZone Duralast Replacement). My problem is when the starter engages the flywheel it
doesn't disengage, yes it makes a awful sound. I assumed that maybe the shims they included were needed, they gave me three. Tried using one, two then three all with the same results. Yes a four hour starter job. I'm no certified mechanic, but I have replaced a few starters in my time (in short I have owned alot of cars that most people would junk). The starter just won't disengage from the flywheel. So my questions are, is my starter defective? Do I need more shims? Or, is there a more common solution that I am missing? Need to get this care back on the road quickly, any help here would be greatly appreciated, In advance thanks to you all.

It could be a shim problem. Could be a broken bendix, dragging solenoid, shorted ign wires, bad ign switch, etc. Jump the solenoid with a wire (key off). Does it still drag? Pull the starter off and bench test it with jumper cables. Be aware that it will flop about unless you hold it down.

Called Autozone, they think it is the shims. It might need more then was included. I dropped the starter down a bit (away from the flywheel) and turned the key. The gear engaged and disengaged freely. Bolted it back up again and still have the same problem with it not disengaging. Just trying to provide as much information as I can.

Sounds like you are on the right track. Let us know what you find out. My car has the same engine.

Hey guys, Thanks!
It was the shims, I had to shim the starter over a quarter of an inch to get it to work. Ran it in work all last night and everything seems fine. The original starter didn't have shims, I would be amazed that a car with 202000 on it would still have a factory starter but it was in rough shape. Once again thanks.

If it is a direct replacement starter it should not need shims, if your factory starter didn't. Are you sure you have the right starter?

I agree. Normally you keep the same shim pack when you replace the starter as you used with the old starter.

Hey believe me, I'm not to happy that I had to add all those shims, with the starter being so far up front in the car moisture getting in is a concern, but I had two stores cross refrence the starter and they both came out with the same one. And I have to get back underneath it. There is a very slight grind when I start the car, although it kicks right in I may need to replace one of the thicker shims with a slightly thinner one (for those that may be doing the same job), so i'll bring it up a little more. Hey wait till I have the dough to mess with the tranny....... that is a whole other story for some other time. Should there be metal shavings in your tranny fluid? : )

Once upon a time I went to replace the rear drums in my car....went to pep boys to pick up a set, brought them home...they didn't fit. Returned them and picked up another set ...didn't fit. Went to Advance Auto Parts, picked up a set.... they didn't fit. Went to Autozone, picked up the cheapest set possible.... they fit.
Later on, I checked the boxes from Pep Boys and Advance Auto. Seems like the same manufacturer was distributing the drums under SIX different name brands !
So the drums cross-reference for ALL these brands would have been incorrect !!! And because many stores carry the individual lablels, no matter which store I went to, the drums would have been incorrect.
As mentioned.... Autozone had only the really cheap set in stock..but they were correct. Otherwise...I would have been chasing my tail.
Don't know if this helps or not...but it's a true story.... maybe your cross-reference is off also ??
