    Float needle

    I had fuel coming out of the bottom carb and it was a torn fuel pump diaphram. As far as I can tell the float needle seat is in the carb and not on the needle. 1. If it won't seal maybe the seal is gone in the carb. 2. You could move the bottom carb to the top position to see if the problem...

    Will a 1977 135hp Chrysler outboard work as a parts motor for my 1974

    Looks like the lower end is different. What else is different between a 1977 and 1974 Chrysler 135hp?

    89 force 125 leaking fuel from carbs

    Double check your fuel pump diaphram. I had a ripped one that when I pumped the primed bulb fuel would spill out of the lower carb and down the exhaust leg. It's easy and fast to check and a week point on these motors.

    Let us know how it worked out!

    Yes so true. I try to always post results of changes I have made. It might get tedious for some but I think the results are the most important thing. Did something work or not. Did things get better or not. Thanks for sharing your results dudes!

    Why would the electrode on a spark plug get smashed

    I like the look of the L20V. The bevel edge looks like it will clear fouling better. They are discontinued. Not sure if there is a comparable Champion. It's hard to know if these motors are running rich or lean. The only adjustment is the idle screw. I think a 1/8 turn can make the difference...

    Why would the electrode on a spark plug get smashed

    Thanks for the input. Yes this happened awhile back but I wanted to get more input on what could have caused it. A few weird things, all the plugs are identical but only this one got smashed, It ran good for a few hours before this happened. there does not seem to be any play in the piston...

    Why would the electrode on a spark plug get smashed

    I installed conventional plugs on a 1974 135hp Chrysler and while running at 3/4 throttle for about 10 minutes the motor stopped running well. I pulled the plugs and found the #3 plug electrode was smashed. No debris in the cylinder and 130psi compression just like the other 3 cylinders. Any...

    Aftermarket epoxy coil that works so far

    It's always good to find aftermarket parts since originals are hard to find and expensive. I got this epoxy filled coil on ebay for $23.75. The title said "Blaster Ignition Blaster SS Coil High Voltage -40,000V Male E-Core Square Epoxy" So far it is working just fine. I bought 2 just in case. It...

    New NGK BR8HS plugs improve overall performance

    Some with the conventional ignition conversion say they run the bent electrode with no problem. I wish I could. I loved how they idled. Well we will see if the L20V's do any better. I triple checked and the L20V is definitely referenced in the shop manual for my motor. Here is a link to the...

    Bad plug wire- 89 force 85hp

    Just to give you a comparison. My 1974 Chrysler 135hp would only get to 4500rpms and 38mphs at WOT with a 19 pitch prop. The boat is a 19ft Winner all fiberglass. Weighs about 1800 lbs. When I switched to a 17 pitch prop it can go to 5500rpms and 34mph. I have done a lot of tuning but these...
