New plug wires, fuel filter, and an oil change today (new filter & Rotella). It's not running any better, it still cuts out and sputters a whole bunch, though it runs awesome for fleeting moments and idles fine. None of this has stopped all bystanders from begging to drive it or go for rides down the street and back... and then followed with everyone offering me cash for it.
I've never, ever, ever, ever had anything people wanted to buy from me so badly. And I'd have never imagined that people would fall in love with a 40 year old Mazda as much as they do.
I'm thinking that I've either got a clogged fuel pickup (doesn't really seem likely, it's not constant) or a bad ignition component (probably the coil). Maybe the carb needs a rebuild, but I feel like it would be a more constant issue.
Also, "Sukiyaki" came on the AM oldies station in the car while cruising around. I felt it was appropriate, haha.http://www.youtube.com/watch?v=C35DrtPlUbc
Another issue I noticed while poking around- the vacuum advance isn't getting any vacuum. I unplugged it from the carb and heard no rpm drop, and felt no vacuum from the carb. Not sure if I should be concerned or not, but I feel like it might be a slight issue. The brake booster is definitely receiving vacuum though, so I'm not sure why it isn't working. It did function ONCE today, for one stop, and went back to not working once again. Ugh.
It scares the bejesus out of me that someone, somewhere ordered the Lusitania with front drum brakes.
