    Sputtering Johnson V4 90hp - 1994

    I had it in a 55 gallon drum cut in half one of the runs. I'll use a drum this coming next time. I'll see how it sounds with my latest cleaning and post the video here. Probably Thursday afternoon/evening PST.

    Hey! were COX Cars and Planes 2-Stroke? I loved the smell of their exhaust. 😊

    I do appreciate all the help. I got myself through upgrading my 65 Chevy to power steering, power disc brakes and an Automatic Transmission with the help of a classic truck forum. . When I was younger, with my motorcycles and vehicles, I always had my uncle, my grandpa, and my dad to help me...

    Thanks, Yes, I had a Yamaha 80 when I was 8. Then a Suzuki RM80 until 1979, then a Husqvarna 250.

    I found a video I made earlier soon after the seafoam. You can hear the sputtering throughout the video.

    . Yeah, my 1984 Suzuki DT 75 was a 2-stroke. And my 1984 Mercury 7.5. And this new to me motor ran how I expected it when I went to look at it and when I got it home. It's definitely not running right since the seafoam. . Let's hope this last cleaning of the carburetors does it. Either way, I'm...

    I've got a DVA on order so I can verify all ignition parts. I just want to rule all out. I'll be doing another compression test tomorrow. I'm kind of approaching this like a service checkup. Just checking everything. May not be needed, but I'm also ordering new spark plug wires.

    I only replaced them a few days ago. I wanted to make sure all 'carbon' went on the old plugs. But yes, I'll check them again and upload a picture here tomorrow.

    Yes, but it only started running rough after the seafoam. But yes, I will get those parts on there.

    I think the seafoam dislodged something. This second cleaning I may have resolved it - hopefully. I won't be able put it back together and start it until tomorrow evening. . I'll video it for how it runs so you guys can hear and maybe better demonstrate the possible issue.

    Yeah, when I first went to look at it to buy it, it ran fine. The videos above are when I first got it home. It ran nice then too. Then I did a seafoam shock treatment, and then it started running rough. I'll try to get a video of how it runs poorly now.

    If I didn't mention it, once I get it running again I'll look it over in the dark for any arcing.

    Good eye! Yes, I have that in my cart for next order - along with the roller on the upper linkage. 😊
