    Suzuki DT75 carb corrosion

    Greetings. My '93 DT75 has developed corrosion in the carb float bowls, which I presume is caused by ethanol gas and the water it attracts sitting in there between fishing trips. I know of no cure for this, so I guess I'll have to replace the bowls. Is there a way to prevent this from happening...

    Suzuki DT-75 idle

    I'm real happy with my '93 Suzuki -- it's smooth and smokeless through the power band -- but it idles too high. It's nearly 1,200 in gear in the water. The idle screw is all the way backed out. Factory manual says to check voltage at the throttle position sensor by plugging in a factory test...

    '93 Suzuki DT75 mysteries

    I'm getting to know my new (to me) motor, which I like very much, but there are a couple things about it that I can't figure out with the Suzuki manual. First, there's a plug on the lower unit next to one of the gear oil plugs that's labelled "Flush." What is this for? Second, I'm concerned...

    Premix in oil injected Suzuki

    I'm finally retiring my '71 Johnson and switching to a '93 Suzuki 75 hp, which seems like a great motor. I still have about 25 gals of 50:1 premix. With the price of gas, I'd like to find a way to use it in the Suzuki. Is there a way to disable the oil injection temporarily?

    '71 Johnson 125 hp low rpm problems

    I'm hoping for some help with an idle problem. This motor runs great over 1800 rpm. Below that, it's tough to keep running. It runs right for a couple seconds, then seems to stop firing on several cylinders. Sometimes it catches again and will idle right for another few seconds, sometimes it...

    '71 Johnson 125 hp -- transom mount

    I got this motor from a junkyard last year. Got it running well and mounted it on my 17' Boston Whaler. I thought it was strange that it only had two holes for mounting bolts. After finding a parts manual, I see why. There's a couple brackets I don't have that are included in what the parts...

    Mid-RPM vibration, 1971 Johnson 125 hp

    This motor's been running great all year, since I followed Joe Reeves' idle adjustment method. But I'm concerned about what seems to be unnatural vibration between about 2,000 and 2,500 RPM. It doesn't miss or anything, just vibrates -- enough to shake the whole boat. Above 3,000 it smoothes out...

    Johnson v-4 low speed problems

    I have a '71 Johnson 125 hp that I can't seem to get running right at low speed. Runs great over 3,000 rpm, but it's really rough below that. I've cleaned the carbs twice (took out the core plugs the second time) and went over the fuel system carefully. New fuel pump, new lines. I just decarbed...

    1971 Johnson 125hp, low speed problems

    I thought I lucked out finding this motor over the winter in an auto junkyard. After rebuilding carbs, water pump, installing plugs, new starter, new fuel pump and a few other things, it seemed to run well enough to install on my vintage Boston Whaler. After much fooling with the carbs, I still...
