    DT50 Suzuki 2 stroke.

    sounds like it is running low on fuel in the carb bowls . not enough fuel to keep up with the high RPM fuel burn . have you tried pumping the primer bulb while the problem is happening to see it that helps? maybe fuel weak pump, restriction in filter or line, or sucking in air at a connection

    Spark plugs

    Spark plugs

    as I said in that other thread, you just use a timing light hooked to #1 plug wire to see when the spark is happening, just like on an automotive motor. cam timing is totally different, you just follower the manual making sure the timing marks line up properly. I have no idea how someone...

    Gas or oil out of exhaust

    that 2017 should be a 4 stroke motor, so no burning of oil. have you checked levels and condition of motor oil and lower unit lube? also might want to look at your spark plugs to see if you see something different on one or more plugs

    Yamaha Outboard SLOW crank! Help!

    200 hp Saltwaterseries lift motor engaging on its own.

    if you have a problem and you disconnect a part you suspect causes the problem and that fixes the problem, that proves it was the problem. then replace it. guessing just causes wasted money seems you do not need to be running the motor or even have it in the water to check
