    Prestolite starter assembly

    They look pretty good. Another $70 shipping to Australia but still. I'll rule out other issues first and then look at getting one.

    Prestolite starter assembly

    Hmm. Only tested armature with multimeter. Had never heard of a growler until now so prop not a definitive test then. The wave washer means that the armature has upwards pressure. There seems to be no freeplay but the shaft will move down and back up if pushed due to the washer. The bosch ones...

    Prestolite starter assembly

    I opened up and cleaned out this Prestolite MKW4001 starter off my 1973 115hp Johnson when I first got it. It was a mess inside and did seem to spin the motor a bit faster after a clean out. I was troubleshooting the motor a bit at the time. Since then I noticed that when the motor has been hard...

    Confused about tank fuel fitting diameter

    I have a 115hp OMC crossflow from the 70s. People say that you should use 5/16" fuel hose or even 3/8" but the brass OMC tank fittings only come with one size bayonet which is 1/4" diameter with 4 little holes in the end where the fuel comes out. The female connector comes in 5/16" or 3/8" tail...

    1983 Johnson 90hp - what happened to this cylinder?

    You mean like blocked jets feeding that cylinder?

    1983 Johnson 90hp - what happened to this cylinder?

    I bought this motor as a parts motor for literally next to nothing. In the interest of learning I checked the plugs. One looked like this. It is from cylinder 1. I then put an endoscope in and removed that bypass cover. The top of the piston was clean comapred to the other 3 (metallic grey as...

    DVA adapter vs DVA analog meter for sensor and coil wire testing

    But wouldn't each cylinder (each sensor wire) be betting the signal less frequently with each additional cylinder. For example would a single cylinder motor running at 5000rpm be getting a much more frequent spark on its one plug compared to each plug on a 4 cylinder motor running at the same...

    DVA adapter vs DVA analog meter for sensor and coil wire testing

    Faztbullet - can you please link to where your info came from?

    DVA adapter vs DVA analog meter for sensor and coil wire testing

    Is it just me or does the spec sheet that Faztbullet posted have an error? The table shows that Black/White to gnd should be 0.6V, but then point 9 says it should be at least 150V.

    DVA adapter vs DVA analog meter for sensor and coil wire testing

    Are you looking up a different motor to mine? I get this straight from the 7th edition CDI troubleshooting guide from the CDI website.

    DVA adapter vs DVA analog meter for sensor and coil wire testing

    Oh it is talking about the stator, not the ignition coil isn't it. My mistake.

    DVA adapter vs DVA analog meter for sensor and coil wire testing

    But isn't that what testing the orange wire is all about? I guess technically it is the signal going to the coil you are measuring rather than the coil itself but test with and without the orange wire connected to the pack is used to identify if the coil is bad.

    DVA adapter vs DVA analog meter for sensor and coil wire testing

    Interesting that on the CDI chart you linked to under my motor (85-140hp 1973-1977) it just says N/A under power coil as in there are no DVA measurements. The CDI troubleshooting guide calls for these various measurements under the same motor: I feel like some of these have been cut and...
