In the continuing saga of my 216 re build, the newest problem is serious misses at higher RPM. It idles great at 450 -500 RPM. Have run the engine less than two hours total over two weeks of working on this.
I have checked and replaced the Vacuum advance, timed with a vacuum gauge and checked vacuum out of the base of the carb. I have gauges installed ay both places.
pressure at the manifold is about 17-18,
pressure out of the base is about 14 - 15
New plastic Carb base, Carter YF carb.
checked Timing ball with a light and it does not give me a good setting
During the rebuild, checked the casting numbers to insure all were compatible and designed for the block, insured the timing gears were properly aligned.
Distributor and cap installed correctly and checked several times.. New points, plugs, condenser
Questions are:
- Bad distributor shaft/bushing?
- Coil on the way out?
- Carb issues?
Any thoughts?
