Re: Super 8 projector - easy fix?

I've seen this problem before on 346 B&H. The upper sprocket shaft is binding. Remove the back cover, remove the upper sprocket drive gear, and oil the shaft until the sprocket moves freely. Try oiling both sides of the shaft and work in the oil by rotating the shaft until it turns nicely. .
The best fix is disassembling the front autoload mechanism enough to move the shaft in and out while oiling, but that might be difficult if you don't know what you are doing.
Just work in the oil till you get the shaft to move freely, reassemble, and the machine should operate well.

Dear NYC Frameworkers -

The Super 8 projector I've got right now isn't consistently working.  It's a Bell & Howell 346A.  Here's a brief summary of the issue:  The top gear which advances the film gives a slightly squeaking noise when starting.  Within a few seconds it slows down to a complete stop.  (i.e., when auto-loading it completely stops before the film is to the gate.)  The bottom gear continues to spin in a regular speed.  The top and bottom gear work correctly when in reverse position, with no slowing.   It worked for one screening of a 3 minute short.  (It's not my machine, so I'm a little cautious.) 

If this isn't an easy fix, I'm open to information on someone trustworthy who can do repairs.
