Mustela Frenata

I'm trying to repair an old Technicolor model 1000 M projector which shows super-8mm cassette films. It has a gear which has many teeth missing, so the film-advance pawl (sprocket?) does not work. I can fix it temporarily with Insta-Plastik, but I'm looking for a more permanent fix.

I have found several camera places on the web which sell the repair manual for this projector, but not the parts themselves. I can't really justify spendig the money on the repair manual if parts are not available anywhere.

Does anyone know of a place that definitely or probably does carry repair parts for these old 1960's/1970's projectors?

Two parts --

My '85 Ford Bronco II (2.8L V6, 4WD, carb, manual) starts, idles, and runs fine when the engine is dead cold, or when the engine is fully warm (temp above the 1/3 mark). But when the engine has warmed enough for the needle to come off the bottom but hasn't yet crossed into the normal range, it won't idle or run worth a darn -- it acts like it is only firing on one cylinder and smells like the mixture is extremely rich.

This is a minor problem normally, but in really cold weather it just becomes a complete dog. I can rig it by slapping a cardboard panel across the radiator -- the engine heats all the way up and it works fine.

But I'd really like to know what is HAPPENING to it? This is the 2nd carb that has done this, so I think it must be from the EEC-IV somewhere, maybe a bad sensor?

2nd question: Anyone ever put a 1990's Mazda MPV 2.8L V6 and tranny into a mid-80's Bronco II (my '95 MPV with 165K always runs sweet)? Any advice if so?
