Hey to be totally honest I’m not sure and still figuring it out, but it’s better. after I posted this in 2024 I didn’t quite fix it, and then the brakes kept going out on me. Garaged the car for a year and a half due to a lot of thing.
It’s funny you messaged, I just worked on it these past 2 weeks and took the first drive since starting this thread. Ended up swapping to dual bowl master cyl, that got the brakes solid for now. Still had carb/ running issues like before. I decided to pull the carb and open it up myself. Went on a rabbit hole of different manuals and images…since I’m no mechanic. My carb (1100 with SCV for a LOD dist) was missing the 4th check ball, the float was a bit too low, and the gasket was not great. Also, the fast idle and choke circuit really was not behaving like it should, I didn’t know this before. And the anti stall dash spot was not screwed in correctly. I just addressed those issues for my first attempt, put everything back together, re timed the car (just back to 12btdc) and drove it today. I have some kinks and tuning to work out still, but it’s driving much better than before!! I’m also now getting 19 inches of vacuum, where I was around 16-17 in 2024. Car Still likes to be really warmed up though. For today I’m happy, and then I noticed the radiator is starting to leak out of the top seam haha! Sorry for the very long update and reply, but I hope it helps! I’ll try to keep track of more things and update if I remember. Please do so as well I’m curious what you find out!
