John deere 420 garden tractor

[cbird]

Went to blow snow yesterday and my tractor wouldnt start. I used it the day before and it worked just fine. Bought new plugs for it and still nothing. Sprayed starting fluid in it and it wont even pop. I have spark and fuel but, it wont fire. I covered it up today with a heater going thought maybe it was froze up or somthing and nothing.
Any suggestions?

How did you check for spark?

Well aside from the fact my Dad got zapped by accident I just took the plugs out and held them on the side of the engine and cranked it over. Its a Kawasaki engine if that helps at all. Its just odd because it was running totally fine when I got done blowing snow on friday and put it away.

Can you post up the numbers off the engine.

Your spark test doesn't tell you if the spark plug is good or bad. Under compression you can lose spark. Always test for spark with the plug in the engine. All it takes is a cheap spark tester which you can buy at most auto parts stores for less then 5 dollars. Plug on the side of the engine isn't a true test for spark, but I just seem to see it all the time on this forum.

Should it not have a Onar and not a Kawasaki engine..?

That is true but, since I dont have a tester I was just checking to see if there was any spark at all and both plugs have a spark and even if one of them was weak it should still fire on the other cylinder or at least pop but, it does nothing.

Disconnect the kill wire at the key switch and then see if it will start, and or check all the safety switchers.
