OK Guys, I am perplexed. Engine was running for a short time, then sputtered and died. I could not see a spark so I changed points (new), and a known good capacitor. I have what seams to be a good spark (when turning over with spark plug laying on cylinder head). Engine will not fire even though I sprayed starter fluid in carb several times and into cylinder directly. After repeatedly pulling engine over I pulled the plug, yup still getting spark. Can a coil go bad and spark outside of cylinder but not under compression? Also butterfly was setup with a spring to the lever as shown, this does not seam right as tesion keeps the butterfly closed even if I move the throttle ?????? Thanks for the help!

Sometimes a weak spark will show when the plug is out (Not under compression) and when the plug is in you get no spark or weak spark.

Put  on an ignition tester and see what happens, If you dont have one they are faily cheap and I can get them if need be.

Yes, it will, 9, 14, 19 and 23 all do that, if the plug is coming out wet with red/orange hue spark then the coil is on it's way out, change it.

Could also be flooded.  Awesome spark won't help you if the fuel to air ratio is to high.  Let it sit overnight with the plug out, or try one of the "hold my beer & pass me some fire" cures.

I should have mentioned, Spark is blue and you can hear it (nice crack)...........will let it sit overnight and try again, but did not even Cough when I turned it over.........totally just dead.  you would think after spayying starter fluid in it you would get something!

Hum, im thinking Brian and Mark is right, try again tommorow by dumping a little gas into the spark plug hole and crank it.

Here's another one that got me for awhile.  I had a great spark with a plug laying on the cylinder head.  It would jump the max I could throw at it.  But inside the cylinder it was dead as a doornail.  I could dump gas right in it, and I even used starter fluid, something I do very rarely.  I only keep the stuff to kill wasps.

 

I finally figured out was causing the problem.  The spark plug wire was broken internally and while it was not connected enough to gain any fire worth enough to write home on the cylinder head, it must have connected while the plug was lying on the engine head.

 

May not be what's happening to you, but it might be worth checking.

Ben, I think that might be it, was thinking that very thing today. I am gonna hook up an automotive 6 volt coil to the points and see if it wants to go....if it does than I don't need to worry about the carb.
