Hey,
i have a problem with my engine, it's running rough in idle mode and when im trying to maintain the same speed.
The car is a 66 Mustang with a 200cui engine with an Autolite 1100, 3-Speed manual transmission, Pertronix ignitor and coil.
I importet the car to Germany a couple years ago.
For now i rebuild the Carburetor, changed the spark plug wires, tried to adjust the timming with a timing light and a vacuum gauge and adjustet the idle mixture screw. Installed a relay to give the coil full 12V. Spark plug gap is set to 0.04. Non of that really helped.
Compression test results are 130-145psi.
When the engine is cold it runs better, ones it's hot it's getting worse.
The sparkplugs 1 and 2 look good - lean, plug 3-6 are oil fouled. Plug Cylinder 1, Plug Cylinder 5
when hooking up the vacuum gauge the needle is flipping around 18Hg. I cant get it to maintain steady. Vacuum video
I appreciate any idea on how to get the engine runnig smooth.
