Question about Spark Plugs BR4HS Plug 10/BX #3322
Was trying to put new spark plugs in motor. When pulling out old spark plugs one of them was stuck and was very hard to unscrew! Put a little more effort into it and then it broke in half leaving the thread stuck in the cylinder head!
What can i do to fix this problem? any advise is welcome!
I did this today, if you are lucky like i was, the core of the plug came out, just leaving the thredas screwed in.if this is the case, just get a stud extractor (the type you screw in bacwards)
that pulled mine straight out, with no issues.

Their are three options; A tap of the proper size may clean up the existing threads. The second , is a kit called a Heli-Coil where you remove all the threads , tap it out bigger and instal a Heli-coil to bring the threads back to the original size. The third is to tap it to the biggers size and then look for an oversized plug. I was able to do this for a lawnmower many years ago and do not know if oversized plugs are still available.
