Again, the float has nothing to do with the starter turning and not engaging the engine. They are unrelated in any way.
I asked specifically,
"When you turn the key switch to the start position, the electric starter motor turns, but it's not causing the engine to turn over? Or the engine is turning over, but not starting?
When you release the key switch, the electric starter motor continues to turn for over a minute, still not engaging the engine? Do I understand the symptoms correctly?"
Your resonse was,
"The engine does not turn over. When I release the key it does spring back to the run position. Yes, the starter continues to turn over after I let go of the key."
If you go back and read the questions and answers, what you are saying now is not what you told me earlier. The information I supplied was right on for the problem you described, but now you're saying it is a different problem?
I'm not really sure what you want from me at this point. I answered the questions you asked accurately and completely, but I can only give answers based upon the information you supplied.
In order for the float to be a problem, the starter first has to engage and turn the engine over. What you described was a problem with a stuck starter that kept turning after you let off the key switch, but failed to engage the engine. That would have been a switch or solenoid. The starter not engaging the engine would have been a bad bendix or spiral on the starter.
I don't think there's anything I can do to help you at this point. If you want further clarification, you might print this conversation out from beginning to end and show it to the technician that worked on it to see his opinion.
