Hello,

i recently purchased a keystone 98 projector from my local antique shop for when my super 8 film comes back from the developers. when i brought it home i ran a roll of test film through it to see how it ran. the film jumped and was also blurry. i did a little research andfound thst it could be the pressure plate. then i went looking for how to adjust the pressure plate and i found that other examples
had a diffrent pressure plate than the one i bought. now, this particular projector had been re-badged to a P.R.O. automatic 8z, but was still made by keystone. could keystone have put in a worse pressure plate so people would buy their name-brand projector or has it fallen off at some point?

Welcome Ben!,

This projector is not for Super-8 film, but Regular 8mm.

-the sprocket holes are a different size and it'll digest Super-8, but can't really project it!

Are you sure the Keystone is a super 8 projector? It sounds like it might be a standard/regular 8mm and there is a difference. The sproket holes are different. Running super 8 in a reg 8 projector would be jumpy and blurry and can damage the film. Don't run your film from the lab until you make sure you have a machine for super 8 film.

PS Steve, you beat me to it!

originally i thought it was a super 8/regular 8 projector and all i had to do was buy the reel adapters because the sprocket teeth were square as opposed to rectangular if it were 8mm only. now i8m afraid that i am going to ask a dumb question and ask if there would have been a switch on the outside of the projector used to switch between the two formats?

Yes it would have had a switch to alternate formats. I cannot post a link but if you go to Phil's Classic Movies on his site he has a pretty informative explanation of the two formats.

Hope that helps!
