    quote John8504:

    The engine at hand is my 74′ ted Williams 15hp motor. I have battled some demons with this one and had major problems getting it to run this morning. I could get it to idle poorly and then in gear it would not rev very well and just die.

    I let it sit for a while because I’m frustrated, 4 hours to be exact. I come back out and start it up on first pull. Idles great! Reverse is great! Forward, no go. Forward has no power and does several seconds after being engaged. Seconds after this video, it died.

    What could be going on?

    John, I have not worked with your Make and Model motor. It seems it is Eska with Tecumseh 2 stroke powerhead. I was looking for some manuals that might help you out. Maybe you already have manuals but I figured it could not hurt to post them for you. Some have diagnostic and resolution charts.

    Even if you have spark on both cylinders, try the drop cylinder test. While the motor is running, disconnect the top spark plug wire from the spark plug. If it dies, then you have spark issues to the bottom cylinder. If it continues running then replace the top spark plug wire back on the top spark plug. Let it run for about 20 seconds then disconnect the bottom spark plug wire from the spark plug. If it dies, then you have spark issues to the top cylinder. This demonstrates that even if you have spark, there may be fault with the coil, condenser or points with the associated cylinder if it can not cause combustion under compression. Please use insulted pliers or heavy insulted gloves to remove the spark plugs wires while running…..zzap gets your attention….lol

    As always, check to make sure the fuel cap air tap is opened and not clogged. This will cause fuel delivery issues and poor running.

    Cheers,

    Hope they help you out.
