RXT Rusted Spark Plugs

[gms05rxt]

Ski started running rough , seemed like a cylinder was cutting in and out.I went to take the plugs out which have over 100 hrs (ski has 340 hrs)and they are rusted solid.I didnt wanna try too hard and break one off.Anyone have experience getting these things out.If I break one off its gonna be a nightmare

That is why I put vasoline and anti seize on plugs when installing them. I would spray lots of wd40 down there and leave it for a week and then try to remove. Chemsearch spray is even better but cost 80 bucks a tin. Just what I would do.

Warm the ski up before taking them out. A little heat almost always helps.
Also after you break them loose but before they are completely out use a vacuum to suck any rust pieces that might fall into the cylinder...
Use anti seize on the new plugs.

If you don't get it out you need to take out the cilinder head,that's wg

That's why a always advise to change the spark plugs every year or every 50 H
