    ok so electrical all ok, compression ok carbs ok throttle plate ok link sync ok yet fuel does not reach it's destination to start the engine ... any chance the crankcase case vacum needed to "pull in" the fuel is low compared to your "5 other working motors". It is a bit ackward to...

    2005 115 Johnson PLSOR dies at idle

    I did not mess with the adjustments, so I assume (or rather, hope) they are where they need to be. actuualy they are probably exactly at the proper place the problem is the fuel crud which blocks a very small passage hence the need to just open up the idle counter clock wise to check for...

    Weak spark from one spark plug

    so you did replace / swapped most parts ... the big variable is current flow to induce a strong spark via the HV secondary that begins when the stored magnetism collapses and the primary coil tires to sustain itself & generates a current flow which ends up in the condenser as the...

    Can the newer hex headed drain plugs be used for the vent plugs?

    HEX head drain plugs a real PITA when they are stripped.... it happens ! you then have to grind slot to take them out or bash the edges counterclockwise... lots of fun . after you do one you never install another one. jmho

    Weak spark from one spark plug

    measure the boot to frame ohms in the slow/idle position of the throttle keep measuring the ohms as you rotate the trhottle and the mag plate truns all the way to fast.... ohms should be rock solid all the way from idle to fast did you change any condensers or coils clean the...
