l not run even with a shot of started fluid ..help me

i have fire to spark plug but it will not fire even with starter fluid

Re: l not run even with a shot of started fluid ..help me

Does it have compression? You need 3 things for an engine to run...fuel, spark, and compression. If you have compression, try a new spark plug. Some faulty plugs will spark outside the engine, but not under compression.

I TRIED OTHER PLUGS THAT ARE RUNNING MY TILLER IT WORKS FINE .THE CRAZY PART IS THAT I HAD IT RUNNING FOR THREE WEEKS ALMOST EVERY DAY .PUT IT IN THE TRUCK AND BROUGHT T TO MY POND BOAT WOULD NOT START .BOUGHT I HOME CHANGED THE PLUG WIRE BUT DID NOT HELP.BY THE WAY DOES THIS HAVE TO BE A COPPER BRAIDED WIRE? IT LOOKS LIKE IT HAS PLENTY OF SPARK .IT LIGHTS UP THE BULB ON MY FIRE INDICATOR LIGHT.I HAVE BEEN WORKING ON SMALL LAWN MOWER ENGINE FOR YEAR THIS HAS ME PUZZLED.....

Re: l not run even with a shot of started fluid ..help me

Yes it has to be braided copper wire core ignition
7mm cable. Other types will not meet the special
requirements of flexibility, routing thru tight bends and be soldered to coil lug if required of small out
board motors.
Was anything changed between last time it ran and
next time it did not start?
If it will not start on ether you can rule out compression and carburetion. Time for a hands on
ignition trouble shooting lesson.
I spray electrical contact cleaner on magneto because
usually upper seal has failed and everything is
coated with hardened oil and dirt.Go thru everything
sooner or later you will do the right thing.

Sheared flywheel key?
look up 7mm spark wire on Ebay if you can't find copper core wire locally.

took out points and condenser

changed to electronic ignition ... at first i had fire put the plug in ..gave it a shot of ether and nothing i am lean toward a bad coil.....but it ran good for three weeks before i put it on my pond boat.after that nothing .what do u think guys.

Re: took out points and condenser

Don't spend the big bucks until you have eliminated
all of the cheap fixes...make sure everything else
is spot on, all connections tight and clean. Coils
may have to be "adapted" to your magneto if suitable replacement can not be found...a not uncommon solution that takes just a little McGuivering.

Coils that look bad sometimes are good and coils that
look good sometimes are bad. A dry coil with cracks
may work okay...same coil exposed to humidity may
lack umph. Ignition coil has two loops of wire and
insulation...wires break anytime and insulation breaks down over time.
