Been a long while offline but have been plugging away at it (have way too many other projects and limited time for it to move a decent pace).
I got TTI exhaust installed, rebuilt the carb, flushed the gas tank and fuel lines.
Did a pressure test on the intake manifold; no vacuum leaks.
Used a dial indicator to map the intake valve travel on #1 and confirmed the cam timing was right. Centerline is at ~107.
Have an off idle pop out the carb I never could fix. Everyone person told me it was a vacuum leak or maybe I installed the timing gear/s wrong. Nope.
Pretty sure it’s carb tune; read stuff on low vacuum engines (I’m at 10”), you can easily set the idle speed screw is to high and you’ll get into the other circuits, and then you will set the idle mixture screws too lean. Gotta check if they are open too much, and the drill the butterflies or something to get off the wrong circuit at idle.
Anyway, drove under its own power about a month ago; first time 12 years. Didn’t even go around the block, but still was great feeling.
Just pulled the booster and had it rebuilt and got a reproduction disc master cylinder to replace the drum one that was on there (has the original 4 pistons calipers; they were rebuilt in ‘96, stainless sleeves & pucks. Will see how they held up).
Think the proportioning valve is probably bad also; rears use to always lock up easy, but will see with this master cylinder on there.
Gotta vac out some old mouse nests i found in the cowl, clean the ducts, and find the heater core leak (disconnected it back then), and get the vacuum operated stuff working.
Wonder if it just from not having enough vacuum for them to operate, never installed a vacuum reservoir/
tank; will now, again have 10” at idle
Am doing that heatercore & a/c stuff now since I had to take so much under the dash apart to get to that one damn booster nut...
Guessing a should do a build thread; any posts/links on best practices for that to help others with similar issues? Am sort of a newb on contributing content to forums.
From Pa left coaster!
