Same spark plugs in both? Gapped the same?
Same coil. Compression the same?
What is the difference in burn rate?
Please post the results to the other questions.
The spark plug gaps are the same....
The compression is different. The port (problem engine) has compressiona at 50 , the starboard is about 30....
Both engines are a problem... Compression pressures should be around 160psi, with no more than 20 psi variant between any cylinders....
