    8hp Johnson idles well, but stumbles under load, sometimes

    Hey Mc Tool! Let's say I first launch the boat. I will prime it and choke it. I will pull it with authority like ten times, and will not even try to start. Once I catch my breath and reattach my arm, I will pull it another five times, and it may pop. I will need to pull it another couple of...

    8hp Johnson idles well, but stumbles under load, sometimes

    Just an update: So, I bought and installed a new oem power pack, and the engine is running like a champ! It's still hard to start when cold, but regardless, I'm so happy I was able to finally get this thing running properly again. This issue has plaqued me for over a year now, and I was about...

    8hp Johnson idles well, but stumbles under load, sometimes

    Hey guys! I took the boat out today, but it was an electric only lake. However, I did poke around the engine and looked closely at the wiring. All appeared to be okay, no chafing on the conductors and the connections that I could access looked good. I want to add that when the engine began...

    8hp Johnson idles well, but stumbles under load, sometimes

    While I didn't pay attention to the timer plate, I did drive around for the entire trip with the cowl off. So, perhaps something wobbling around would've caught my eye? I no longer own a timing light, but I could ask my friends and co-workers if they have one I could borrow. Part of the problem...

    8hp Johnson idles well, but stumbles under load, sometimes

    Hey saltchuckmatt! I unscrewed the slow speed needle (15) and shot a bunch of carb cleaner through it. I did eyeball the main jet/high speed orifice (24) but I couldn't budge it using standard power 😁 (I didn't want to booger the slots in it) but I did shoot a considerable amount of carb cleaner...

    Copy that! I thought you were talking about the spark plug wires :) So, I need to check the connections between the stator and the power pack first, then replace the power pack if the connections look solid, correct?

    8hp Johnson idles well, but stumbles under load, sometimes

    Thank you for the replies! In part, I'm trying to determine if I should put money into this engine or get something newer. racerone, plug wires and the power pack are two areas I have not addressed. Those components would cost me around $150, not too bad I suppose. I have a video of this engine...

    8hp Johnson idles well, but stumbles under load, sometimes

    Hello all! I have an '85 8hp Johnson that will start, idle, and run fine at a slow speed, but will cough and sputter (badly) once the throttle is opened. If I continue to operate it in this condition for 5 - 10 minutes, the engine will magically and instantly begin to run perfectly, as if...
