    Does anyone have tips as to how to best start one of these motors when it has just been stopped?

    If the motor is in good tune it should only need a single pull of the rope when warm. Anymore than a few pulls and it’s probably flooded. Close the fuel needle, set the carb lever to fast, timer at 6 o’clock and pull the rope until it starts. That’s been my experience anyway. I just happened to work on three of the A series motors this weekend.

    I had an OA-60 a long time ago, and it liked it rich when restarting, even when hot.

    That bein’ say-ed – these things also tend to flood easily, my P-30 is picky that way. Any hot re-start after even the briefest of shut-downs usually requires closing the needle valve then reopening it after the engine fires up.

    By contrast, my F-70 is a good girl, and requires no special treatment to get started, hot, cold, or anything in between.

    All of my A series Johnsons (I consider the BN to be one of them) are good at restarting on the first pull when warm. I do habitually turn the fuel petcock to closed anytime I shut them down, even if its only going to be for a few seconds. The exception to the one-pull rule seems to be Johnson # 3999, which I currently have apart. When it was warmed up, it was still necessary to choke it and open the needle valve to get it to re-start. The piston rings were stuck in their grooves on the starboard side piston, so I wonder if that was a contributing factor.

    I’m assuming your OA is an easy starter when cold?

    Best,
