I'm having issues with my new RV 7 engine. The fresh majored 0-360 runs very rough. It will not develop full power, either. So far I've confirmed that the dual pmags are firing and timed correctly. Compression is good. At run up, all cyl head and EGT temps rise and fall together, evenly, so I believe all jugs are firing. But the engine is very rough. I'm now investigating the Ellison throttle body installation, as I'm out of other places to go. Any other thoughts? This is a new install on my newly finished 7, fresh gas, new plugs all fire well, fresh gas, etc... Any thoughts?
