I'm with Robert3727, I had a 1996 Evinrude 8hp doing the same thing. Did everything to the carb until I got a new power pack; it solved all the problem. Enjoy the way you demo you videos and honesty.

@masterful7574 Жыл бұрын

You need to change the exhaust tube also to change it to a 15. Is there a leak in one of the seals allowing air in?

@dirtybuzzard5977 Жыл бұрын

Sounds to me that its getting too much air maybe turn out mixer screw another 1/4 or 1/2 turn . How about just trying the 9.9 carb on it . Another great video love the Ol Johnsons and Evinrudes . As always Sir thanks for the ride along and Keep’em coming 👍👍👍👍

Thanks for another informative video. Like many others I'm leaning towards a fuel delivery problem but it's really strange that it would occur with two different carburetors having the same symptoms. As far as the ignition components there is a video out there on KZfaq by wet shoes mechanic that shows how to test all the ignition components with just a simple volt ohm meter if I remember correctly. I'm sure I have it saved in my saved videos if you can't find it. Keep up the awesome work, looking forward to the resolution video.

Fuel pump leek or a gasket under the carb/motor side, or a leek in the fuel line. Carb is sucking air somewhere. Sounds like it's running lean, especially when it's accelerating.

@lars9631 Жыл бұрын

To me, it seems like an air leak somewhere. Pulling the choke forces more fuel in and it runs longer. Check under the flywheel for a crankshaft seal leak. Or maybe a bad fuel line.

Definitely fuel starvation. If fuel pump is not leaking air then your fuel supply to the carb is being impacted. Is the tank vent open? Is your fuel line liner collapsing? That could cause a vacuum on the fuel going into the carb starving the engine which would improve slightly when you choke the carb increasing the velocity by Venturi effect. Lastly a vacuum leak in the carb, bad gaskets or a plugged air bleed passage again not letting the fuel to flow properly. Good luck, those are things I would try.

Found your channel today. Working on a Johnson 9.9 1976, gear oil seals are worn out. I've already snapped 2 bolts, and broke a bolt flange on the bearing housing (urg). I cannot get the lower unit to separate from the motor. There where only 4 bolts, so I'm guessing someone, at some point, snapped 2 of the bolts, and maybe that's what's holding it up. It's a pain in the behind working on restoring an old motor, that has not been taken care of.

@Michaelsbackyardmarina Жыл бұрын

sometimes the broken bolts can be corroded on the through hole area, good luck and thanks for watching

@RK-qv2nb Жыл бұрын

Just that happened to me on an old outboard amazing how the crud prevented the separation. One bolt came out part of the way then snapped. The remaining piece of the bolt was loose came out by hand once the lower part as separated.
