    8hp Evinrude running poorly.

    Is the emulsion tube the little rubber tube that runs down from the idle jet to the well, or the brass tube that runs down from the middle of the carb that the well surrounds? After looking at the fuel pump further and taking it apart again I ordered a replacement pump from Sierra. Whatever is...

    8hp Evinrude running poorly.

    Right?? We'll see how it turns out. And that is assuming there is something wrong with my carb in the first place. But I don't know what else it would be at this point.

    8hp Evinrude running poorly.

    I think the year the seller listed must be wrong. The main reason I bought it was after seeing the part # on the plastic top plate is identical to the one on my carb, and everything else looks identical, minus the choke thru-pin. Here are some pictures for comparison: My carb: Carb I...

    8hp Evinrude running poorly.

    Of course I said I was not going to spend more time or money on this thing until I got it out on the lake, but curiosity has gotten the better of me lol. I took the fuel pump completely apart to check it out, figured it was possible one of the little diaphragms had ruptured that could possibly...

    8hp Evinrude running poorly.

    For what it's worth the one curious thing I find about this carb is the fact that the mixture needle needs to be around 6 turns out to get it in the sweet spot. The manual says to start tuning at 3 turns. This thing won't even pretend to stay running at 3 turns. Running too rich would explain...

    8hp Evinrude running poorly.

    New ignition coil got here today. Threw it on the motor, nice blue spark will jump a 3/4" gap no problem on both cylinders now. Starts much nicer at low RPM now that both cylinders are getting a strong spark. Will also start and run briefly with the choke completely on now which it wouldn't...

    8hp Evinrude running poorly.

    Yeah if I could get the OEM parts here as fast as I can aftermarket I would do everything OEM. Definitely worth the extra cost, unfortunately when ordering parts online it seems I can get most aftermarket parts in 1-2 days whereas OEM take 4+. Kinda makes it hard time wise for diagnostics...

    8hp Evinrude running poorly.

    Thanks, when I had the flywheel off earlier thats what the charge and sensor coil line up with on my motor as well. So here are the results of the testing with the DVA - charge coil voltage is around 275 volts at cranking. Down a bit from the 300+ taken with the Fluke on peak mode. Sensor...

    8hp Evinrude running poorly.

    Quick update... just got home and threw the DVA adapter on the multimeter and tested the sensor coil again - still getting a relatively high voltage (13-15 volts) from the sensor when giving starter rope a good pull. Seems way higher than spec which the manual says is around 3 volts. I think...

    8hp Evinrude running poorly.

    I don't think it was arcing out the plug wire. I had it pulled out away where I was planning to hook a lead to it to ground it out, but forgot. I heard it arcing from somewhere, but I'm not sure where it was arcing to. Curious if it's normal to hear the coil discharge to something when it...

    8hp Evinrude running poorly.

    Dumb question, I disconnected the plug wire on one cylinder when I was doing some testing. Forgot to ground the plug wire out. I could hear the zap coming from the coil while it was running. Shut it off as soon as I heard it and realized I forgot to ground it. The running issue has been...

    8hp Evinrude running poorly.

    Gotcha. I'll try to get another video of how its behaving. It does start great when warm. Is the exhaust cover under the plate that has the weep hose for the water pump attached? Will try to get some verification of the actual idle speed I'm running at. I am guessing i can test the coil...

    8hp Evinrude running poorly.

    Interesting, I can put a scope down there and take a look. I'm not very familiar with these 2-strokes, especially on an outboard - I take it I can see the skirts through the exhaust ports? What covers, etc., need to come off to gain access? Haven't looked through the powerhead section of the...

    8hp Evinrude running poorly.

    I saw that procedure in the service manual for the below 5HP models. For the 5-8HP models, this was the "test". 8. Start the engine and allow it to reach normal operating temperature. Shift the motor into forward gear. Rapidly advance throttle to wide open position. If the engine stalls or...

    8hp Evinrude running poorly.

    Thanks for the reply, from what you saw/heard in the video do you think the engine seems to be running well, especially while under mid-range rpm? I unfortunately don't have much experience with 2-strokes to have a good ear for how one should run. It feels rough to me at times, but maybe...

    8hp Evinrude running poorly.

    Yeah I realize the barrel is not ideal for testing. Unfortunately the lake isn't close by, and the engine acts up in the mid-higher RPM ranges, and the barrel isn't exactly good for that. Even though its bogging, I feel like it shouldn't start missing/4-stroking? I'll link a video of it...

    8hp Evinrude running poorly.

    Yeah had it out on the water. Same rough running, seems to idle OK and if it can get up on plane, smooths out at high RPM. But anywhere in between is rough.

    8hp Evinrude running poorly.

    1994 Evinrude 8hp E8RERE: Still fighting this motor to get it running right. It starts easy cold or warm, when cold it seems to like 1 pull on choke, one or two pulls no-choke and fires right up. Once warm starts easy with no choke and some throttle. I have a service manual for this exact...

    Console steering/throttle for small inflatable

    I have a small Seabright 270 8' 10" inflatable that I would like to set up some kind of console steering/throttle system on. I plan to use a 9.9 4 stroke, but all the short shaft models I have looked at are only available with tiller steer. I know Yamaha has control boxes that can be used for...
