In short, you shouldn't expect to see significant changes in the appearance or condition of new spark plugs after only 5 minutes of idling.
This is what I’ve read. Everyone else is saying plugs look normal as of now
It may sound like that on the port side because the starboard side was covered by the board the engine was sitting on. It always sounds weird on muffs. I was concerned it seemed a bit too shaky but maybe that’s normal
The plugs were put in yesterday so they are new. I’ve only ran them in a tank and muffs. I haven’t had it on the water. So the plugs might not tell us much yet
It revs up nice and is smooth. Returns to idle the same. I plugs are brand new so we may not be able to tell much yet since I’ve only ran them since yesterday
Plugs are in order as they appear. The left ones are 2 and 4 cylinders and the right ones are 1 and 3 cylinders. I did clean off the 2 and 4 cylinders yesterday. So they might me a little cleaner then 1 and 3 because of that
