O.k., I've always considered myself a fair hand around a pre-computerized automobile but this has really got me stumped! Let me back up to the beginning of this head scratcher.... I picked up a '51 Oldsmobile several weeks ago that ran fair but had an over fueling problem. No big deal, right? That's what I thought anyway, tried adjusting it and such but nothing that I did helped. So, I took the carb off and took it to a rebuilder that I have used many times over the years. After a couple of weeks I picked up my carb and merrily went about putting it back on. It started right up but after a couple of minutes it started loading up and belching out black smoke from the exhaust and fuel was leaking out of the bodies. I called my rebuilder and explained everything to him, he suggested that I do a fuel pressure check before I take it back off and head back to the big city (a 100 mile round trip). Here's where it get's interesting... Turns out that the fairly new dual action fuel pump was putting out 10 pounds of fuel pressure to a 2 barreled completely stock 303 engine. O.k., so I put a fuel regulator on it and while I was adjusting it, I had the wife cranking over the motor, I hear a loud pop! After doing a visual check and finding nothing I had the wife try to start it again and nothing, just a single click from the solenoid. I pulled the starter off and bench tested it, the starter drive gear would kick out but the starter wasn't turning. I took the starter apart and found that the armature had over spun (I'm guessing that's what happened) and came apart at the windings. Another trip to the big city to get my starter rebuilt, they replaced the armature, field coils, end bushings and solenoid. The brushes looked like new so they weren't replaced. I reinstalled the starter and gave it a try, it could barely turn the motor over and it had a growling sound as it was trying to turn the motor over, it acted like it had a bad battery. I took all the spark plugs out and turned the motor by hand, no problem. I tried the starter again but it is still doing the same thing, barely turning and growling. Took it off and made another trip to the city, they replaced the armature although it checked out o.k. but the noise was gone and it worked great on the bench with 12 volt's applied, they had no way to check it with 6 volts. Put it back in and it slowly turns the engine over and, sometimes when I try to start it, it will just click. One single click! I have replaced the battery, checked and cleaned the battery cables and replaced the wire from the neutral safety switch to the solenoid. I don't know what to do now, spring for another starter or ? Any idea's?
