1986 Johnson 30hp - Vacuum lines and throttle control rod

Perhaps an issue with reed valves and / or crankcase compression??----Sorry, I can not see or touch your motor.---Just adding some things to check.

That's a pretty big issue there. I'll have to look at the manuals to see how to check all that.

When you did the carb do you recall seeing the nozzle gasket? If so did it go back in? If unsure you will see it on a parts page. Have seen a few of these over the years that people leave out thinking they aren’t important.

Down under humor...someone pass the salt.

Good callout, I did make sure it was on. I'm using the one that came in the oem kit, so I'm assuming it's a good one.

Your terminology sometimes gets me...so let's double check a few things. Your low idle circuit screw, how many turns out is it? When you do the link and sync....the step of when the butterfly's open, that is supposed to be at the two notches on the timer plate...some have one.

You never want that to be on the right of those notches when staring at it from the front. On my 85, Evinrude service bulletin, you can be up to 1/2 inch to the left. They really want that timer plate moving first. That's also the low idle adjustment.

Can you confirm?

To check the reeds, hold your hand over the carbs and see if gas is spraying on your hand.

Well I it’s time to take a peek at the reeds. A some first test would be to put a pice a of paper in front of the carb while it’s running and see if it spiting fuel back at ya.
