I NEED TO KNOW WHAT SPARK PLUGS I NEED TO PUT IN A JD 420 LP. THEY SEEM TO BE LARGER THAN WHAT THE JD DEALER SAYS THEY SHOULD BE.

Autolite 216 are an outstanding plug for LP's and working gassers. 437 for oil burners that just putt around.

i ask for information about plugs for a jd420. i should have said a jd 720 lp. checked with parts houses. they say it uses a d21 plug. this plug is 18mm it seems to be too small. it will not fit. could it have a diferent head on it. the plugs that were in it were only screwed in about one or two threads. thanks for any help.
