    How to test VRO system

    Start it on a measured amount of fuel in a portable container. This fuel should have 50 to 1 oil in it just in case the vro is dead. Then put in a measured amount of oil in your own contraption with a clear tube feeding it. After idling it for awhile do the math. At idle it should be between...

    Evinrude 9.9 carb question

    If it stays running with the needle all the way in then something is wrong obviously. Something not sealing the fuel or maybe the float is off.

    Evinrude 9.9 carb question

    The roller shouldn't go on the plastic top??? Original motor had the front needle as well so I'm confused. Is part 21 installed and in good condition?

    Bad rectifier or stator??

    Agree with above. Do an ohm test to the rectifier....it could be toast now. At idle not much voltage is made.

    What are the heat numbers....the same? I'd pull the gearcase and try to reverse flush with air or water. Most likely need to tear it down. Do you live in mud dobbers country?

    1978 Evinrude 70HP- Trouble starting/idling/bogging under load

    Your temp wire and horn are working.....but you don't know if your temp sender is. It's probably fine but buy a cheap IR gun at harbor freight and shoot the top of the head after warm up. Poor man's method is to put your hand on top of the head....should be hot but not scalding. IR gun...

    1978 Evinrude 70HP- Trouble starting/idling/bogging under load

    The alarm sensor, which is just an automatic switch that grounds the horn located up at the box or dash when your motor reaches 145 to 150 degrees, is located with the right arrow. Pull apart the black rubber cover on the wire or stick something long and skinny that's metal in it and ground it...

    1978 Evinrude 70HP- Trouble starting/idling/bogging under load

    I strongly disagree. The motors running good just replace all the maintenance items and there's not a lot. Gear oil, yearly. Spark plugs, when they're needed. Numerous grease points including the prop shaft. Any kind of fuel lines that don't look good, and water pump impeller or entire water...

    1978 Evinrude 70HP- Trouble starting/idling/bogging under load

    Choke is for start up only....on a two stroke you want it off right away. Assuming it's an electric and manual choke maybe the solenoid is sticky. You push the key in while turning to activate a electrical choke. Not sure what you have.
