Spark plug cross threaded
After removing spark plug and cleaning it went to put it back in and was having a difficult time. I was able to get it about half way in, I think the threads got crossed what should I do at this point to correct this kawasaki engine fs541.

Helicoil
I am embarrassed to say that I don't know exactly what a helicoil is. However, years ago I tightened a valve cover on my motorcycle to tight while it was hot, stripped out the threads, took it to the shop. They put a helicoil in it. Fixed it and it worked for years.

Use a sparkplug thread chaser... Or..Helicoil it... In either case..make sure to blow all the shavings out of the cylinder before you try to start it.

Just an added tip to Slapper's post that works for me--load the grooves of the tap or thread chaser with grease gun grease. The grease will pick up all or nearly all of the metal removed and prevent it from entering the cylinder. Follow up by blowing out the cylinder as a further precaution.

Next plug you change add a little anti seize to keep the aluminum and steel from welding together. Always start spark plugs or any threaded fastner for that matter by hand. If it doesn't go in easily, something is wrong.

I have even used a piece of 3/8 hose and slid it down over the spark plug in hard to reach areas. If the plug doesn't thread right, the hose will slip around the plug and not cross thread.
