Possibly, Ms441 will be 14mm plug size, the Ms362 can be 14mm or 10mm. Whatever the size is use the stepped tap.

 

Here is the range of taps and you can get the correct length helicoils from virtually  anywhere.

Hi, it's worth mentioning that with most engines you can get at the inside of the fitted helicoil to tinker with any ragged edges but a bit trickier on a saw's pot, one of the main failings I see with spark plug repairs is the helicoil over inserted slightly leaving a bit of it protruding into the cylinder which ain't great...

Also on such a short thread it's important to get it straight as already said and also use a proper cutting compound or the thread can be very ragged and affect the fit.

I use the original Armstrong helicoil kit and made jigs to guarantee the insert goes in true to the face but if your doing it for the first time you definitely want the pilot nose tap....I'd take a helicoil over a timesert every time...all the best.
