Spark Plug Pipes M96.20

[Mark_T]

I tried the transom plug and it kinda worked some of the time but I had a problem getting it to grip tightly enough. what worked really well was the 1" rubber arbor from my drum sander kit. It has an actual nut for compressing the rubber rather than just a little twisty bar like the transom plug.

When I did this job I replaced all the tubes and all the o-rings. Even if you only want to replace the tubes that are actually cracked (a decision you would likely come to regret) you should still replace all the o-rings while you are in there. How long do you want to spend chasing plug tube leaks?

I know I sound like a broken record on this, but I would really encourage you to do a search of the forum on this topic (top bar, "Search" with a little down arrow beside it). There have been several threads that I think you would find helpful.
