Squealing upon starting....

[RRW]

I put my early 30 Model A in storage the end of May, removed battery.
It was running fine at that time.

Today I reinstalled the battery and it started on first 'try'.
However, it immediately started to squeal and did my next 2 starts, also.
I turned it off immediately each time.
The fan blades are almost immovable by hand and I noticed on a quick 4th start they did not rotate.
It DOES start !!!
Water pump packing nut is tight.

Thanks in advance for any suggestions.
