An unofficial chapter of the popular Dull Men's Club.
1. Relevant commentary on your own dull life. Posts should be about your own dull, lived experience. This is our most important rule. Direct questions, random thoughts, comment baiting, advice seeking, many uses of "discuss" rarely comply with this rule.
2. Original, Fresh, Meaningful Content.
3. Avoid repetitive topics.
4. This is not a search engine
Use a search engine, a tradesperson, Reddit, friends, a specialist Facebook group, apps, Wikipedia, an AI chat, a reverse image search etc. to answer simple questions or identify objects. Also see rule 1, “comment baiting”.
There are a number of content specific communities with subject matter experts who can help you.
Some other communities to consider before posting:
5. Keep it dull. If it puts us to sleep, it’s on the right track. Examples of likely not dull: jokes, gross stuff (including toes), politics, religion, royalty, illness or injury, killing things for fun, or promotional content. Feel free to post these elsewhere.
6. No hate speech, sexism, or bullying No sexism, hate speech, degrading or excessively foul language, or other harmful language. No othering or dehumanizing of anyone or negativity towards any gender identity.
7. Proofread before posting. Use good grammar and punctuation. Avoid useless phrases. Some examples: - starting a post with "So" - starting a post with pointless phrases, like "I hope this is allowed" or “this is my first post” Only share good quality, cropped images. Do not share screenshots of images; share the original image.

Thoughts on putting anti-seize or dielectric grease on the replacement plugs?
Never, ever, ever put antiseize on a plug.
👍
I'm just about to attempt this job and two separate videos mentioned it, thanks for the confirmation
Anti-seize no, dielectric grease yes.
That's also questionable. Rotax went through a ~5 year phase where they recommended dielectric grease on spark plug threads and applied it to newly built engines. After that, they did an abrupt 180 and issued Technical Service Bulletins saying not to reapply it when replacing spark plugs. And AFAIK, they stopped using it in new engines.
I use Rotax as an example because I trust their tech. They make some of the best engines in everything from aircraft to motorcycles.
Also I note your original plugs did not have dielectric applied.
correct, they did not, since I was swapping the coils this time around it was recommended to me so I added a pea sized dab to each coil before I installed them.
Yeah, honestly I never saw issues one way or another, but I assumed they had good reasoning.
Afaik, that's generally discouraged. You want a good seal and ground.
