Thanks Chris, I think I'll have time to look at it this weekend and I'm to going focus on determining if I can affect the issue by affecting things in the fuel system. See what I see and then see if I am more confused or less (:

One other thing though is that I changed the fuel pump in spring of last year and the car ran fine until around the end of fall last year. If it was just a fuel pressure problem I think it would have started at least when I changed the pump.

Well that would be helpful if the higher pressure doesn't actually mess the carb. up. It seems to me I read something on here about affecting something in the carb. long term but maybe not. I'll read through more posts about it when I have more free time and see what I find.

Thanks also dlb, I am going to look into the fuel system as a source of the problem when I next have enough time free. Putting a FPR in was on my to do eventually list but eventually didn't come yet. If that is the issue I don't know that it is directly the problem or if there are some issues in the...

Thanks Mark. I took too long between logging in and writing the long reply I wrote out and I got logged out and the reply didn't save. I'm heading into work so short reply is: Thanks, That helped. Your ideas gave me more ideas.

Hey everyone, I've been having some issues with my '83 SR5 and I'm looking for ideas. The car came with Weber and I got the vacuum sorted out to what is recommended on here in FAQ. After that I got it timed to around 10* BTDC. I plugged one port on vacuum advance (two port unit) as appeared to leak....

That makes sense dlb from what you have noticed as far as oil being likely a strong factor in the diaphragms deteriorating. Does the distributor have to be on the car for any of the component tests? I tested the one that was on the car before removal to the best of my understanding and what I came u...

I did get it. But I didn't check it thoroughly yet. I am curious about the vacuum advance diaphragms though. Since the car was "only" sixteen years old when the distributor came off I wonder too how the diaphragms are and if they handled the sitting around without deteriorating. I'll plan ...

I was looking for a used distributor for my '83 SR5 and found one listed on car-parts.com for a place about seven miles from where I live. I was a little surprised on calling the place to find they still had the part as I live in NE Pennsylvania and don't expect salvage type yards to have parts for ...

I just got a new one too: 257881910230352338. Expires March, 8, 2024.

Yes, that 450,000 was what I was going for with mine until the hydroplaning incident... Also neat that it sounds like the reliability of the Corollas lasted past the nineties. Sounds like yours got better fuel milage than mine did. I have two mostly functional wagons, the Tercel and a Sentra (first ...

Thanks Richardred2, I had tried to get a copy made at one hardware store and had the result dlb mentioned. The closest blank they had wasn't close enough. I ended up finding my second key so didn't try again but the one key is very worn and if I lose or break the newer copy I may not be able to get ...

Hey dlb, Thanks for letting us know what you found.
And thanks to Sirfoxx for the tip about what can cause gear oil to get dark quickly. That is something I am going to keep in mind.
