What spark plug does my yard man lawn mower take? here are the numbers off the engine 110602-0131-e1

it will have a lead going to it with a plug cap on end this cap sits on spark plug.

The dead-man switch on the lever (that you have to hold in to keep it running) has a loose connection or you have a loose spark plug wire.

I don't find that model number in my book.. what kind of engine does it have.

if its a honda engine then it will probably be either a BPR4ES OR BPR5ES

Look in front of engine. Your see rubber coated wire. Unplug it, and there your plug.

look at the old plug numbers are on it ,if you dont have the plug or if you think its not the right one homedept,lowes small engine repair shop can cross ref the mod# cc the can hook you up

That is the intake tube. You have to remove the rewind starter housing and the armature (what the sparkplug wire is hooked to) and unscrew it. IfI knew the engine model and type numbers, I could tell you the part number for the tube. They are located around the spark plug and stamped into the cover. Model-Type-Code.

The three most common causes (IMHO) of your problem are: 1.) Carb (dirty or gunked up) 2.) Gas (old, maybe has water in it, or wrong octane/type. ie., no e-85 in mower) 3.) Spark plug (worn may need replacement, or gap checked) Lawn mowers are simple internal combustion engines. Like any other, all they need is spark, air/fuel, and compression to run. Think about those three things as you trouble-shoot. I hope this helps.
