    1996 Evinrude V6 150 (60 deg) Looper Problems

    Racerone, You obviously have a lot of experience with these motors. Are you a trained tech or self-taught? Regardless, and for what's it's worth, I'm VERY impressed with your knowledge....and thankful for sharing it. Again, I was told yesterday by a local dealer (and others), the problem with...

    WOW! What a relief to learn that! I guess my new course will be to the lean fuel delivery issue!! I wish I could repay you (and others) for your help. Thanks again and again.

    1996 Evinrude V6 150 (60 deg) Looper Problems

    I want to say; regardless if I can get this motor operating correctly, I am VERY, VERY appreciative of the response I've received. Likely, most boaters have experienced the same or similar frustrations. That said, the response from this website and THT has been exemplary....particularly from...

    1996 Evinrude V6 150 (60 deg) Looper Problems

    I just replied to Racerone. Based upon what you both have said, I can rule out low compression as a source of the problem. Compression was 90 psi in all cylinders. It seems the problem is strongly pointing to lean fuel delivery. Btw, I seated my carb seals in the exact same manner as you...

    1996 Evinrude V6 150 (60 deg) Looper Problems

    Racerone, Thank you for telling me that. I guess I'm still thinking 4-cycle, as in valves. What initiates the Quickstart cycle? Is it strictly controlled by engine temp? So, from what you have said, the problem is pointing more and more to a lean condition. Do you agree? If so, I'll again...

    1996 Evinrude V6 150 (60 deg) Looper Problems

    The following are the latest attempts to obtain a normal idle. For the third time, I retraced my steps at synchronizing carbs and linkages. Per manual procedure, I re-checked timing pointer. It was right on. I checked throttle plates and synchronized carbs linkages. I set low idle and high...

    1996 Evinrude V6 150 (60 deg) Looper Problems

    Thanks for the moral boost. I was beginning to wonder if 90 psi compression indicates internal issues. Although a few folks have stated the compression is too low, I've read (one of the manuals) the V6 Loopers have a lower compression than the CF models. Thought maybe reeds could be an issue...

    Sounds like a lot of fun! Just be careful!

    I would think your 17’er would scoot very well with one of those V6’s. Where are you located? Perhaps you’d like to add a 3rd member to your Evinrude V6 collection. Ha.

    1996 Evinrude V6 150 (60 deg) Looper Problems

    Racerone, I rechecked carb throttle plate synchronization. Throttle plates are completely closed. I found one discrepancy. The spark lever and throttle linkage was not properly adjusted. After re-reading the procedure for spark/throttle pick-up point adjustment this morning, I think I may...

    1996 Evinrude V6 150 (60 deg) Looper Problems

    That’s a very positive view of my motor. At this juncture, it’s difficult for me share your praise for it, regardless of accuracy. I admit; I have succumbed to a very low opinion of the machine. OTH, I’m certain the failures are mine….and not those of the motor. Perhaps, you may have more...

    1996 Evinrude V6 150 (60 deg) Looper Problems

    Thanks. That makes sense. I will check on throttle plate positions (and linkages) and proceed from there. If OK with you, I'll reply with any success....or failure. Thanks again.

    1996 Evinrude V6 150 (60 deg) Looper Problems

    Thanks for your reply. If motor runs at 1200 RPM during "quick start (QS)," and assuming carb throttle plates close when "QS" shuts-off, why does it stall? Or, are you suggesting, the throttle plates are not closing completely, prompting a "rich" condition? Note, I can keep it running (at 1200...

    1996 Evinrude V6 150 (60 deg) Looper Problems

    If that's the case with idle timing, then why is idle timing even adjustable? So, are you're saying that I need only to adjust max advance timing? If engine stalls when throttle linkage is manually actuated, a lean condition must be the issue....or timing is not advancing accordingly. Correct...

    1996 Evinrude V6 150 (60 deg) Looper Problems

    Chris, Sincerely appreciate your continued responses.....REALLY! When I sanded the carb bowls, I used a flat piece of hard material to assure level sanding. Although I think I got the surfaces level, I refrained from excessive sanding, thinking that gaskets would make-up deviations. Also, I was...

    I should mention; the compression was tested cold. That said, I will check again after motor has run and reached normal operating temp. Likely, the numbers will be a bit higher. Thanks for your input.

    Spark plugs have been changed 2X and are Champion QL78YC with new (gray, as specified) ignition wires. Haven’t tested the cut-out. I certainly will try it. My original setting after rebuild was 5 turns and starting issues, I readjusted to 5-1/2, which made no discernible difference. That...

    1996 Evinrude V6 150 (60 deg) Looper Problems

    I bought boat/motor two years ago. It had NOT been used for about 8-10 years. That said, I thought I was prepared for some work. Little did I know. Before attempting to start, I fogged the motor and made certain the crankshaft freely rotated. After a few basic tests, I found the motor had no...
