How can properly check the spark on a lawn mower engine. I used to just hold on and pull and if I got a jolt it was ok, but I really want to check to see if there might be a more accurate test. Someone had suggested holding the lead a 1/4 inch from the crankcase and look for a blue spark.

Thanks,

oneputt, that sort of gets your attention doesnt it?? loll.........i used to test spark by this method, or using a screwdriver, til i ran across a handy little spark tester that eliminates the hassle. just unplug the spark plug wire, connect the tester to the plug and wire, and proper spark shows in the tester......it sure saves on frazzled nerves.

They should be available about anywhere, but heres a link to one similar to what i use. http://www.cvfsupplycompany.com/inigspartes.html

(moderators, the add link function doesnt seem to be working tonight)

Maybe Link?



SP,
Does it look lik this?

The one I use looks like a pen with a section the shape of the wire cut out of it. But it takes two hands.

Rob

thats very similar to the one i use

SP,
Don't ask, I have no idea.

I'm glad to hear the testers work well though.

Thanks guys.....you've saved my last frazzed nerve....

Oneputt---The best way I have found is with a Spark Tester.  They can be bought at most any shop.  They do a much better job than holding the plug wire plus much more comfortable.  Hope this helps and may God bless you--Will
