I just came across this video tonight, you might enjoy it.
August 22, 2023 at 11:42 pm #279582I will have to put some sealing in the tank, as I saw a
few drops coming out from exactly where you said. I
have heard that it doesn’t matter the polarity of the
battery, but I did not know it could help with the
points, so thanks for the tip. I’ll plan on getting a
video of it when it runs.
This is what I have been using. I’ve been doing two coats.
Use something like this to clean out the tank. You want it
strong enough that it foams out the fill hole. It has acid in it
and it will etch the tank. The motor in the video was on the
boat for over a month and never had any problem with the
sealer failing.

Something else I want to share with you.
This brass screw pushes against a plastic plug
that puts tension on the mixture screw to keep
it from moving. As the plastic plug wears the
screw keeps getting tightened, but if you go to
far the screw gets stuck. As its brass one side
of the head breaks off (see picture) and you
cant get it to back out. To avoid this snip off a
piece or 2 of the plastic line from dads string
trimmer and drop them into the hole between
the screw and the plug. Just add enough so the
mixture screw has tension on it again.

Watched your video. I believe your starting
and running issue is ignition rather than the
carb setting. Points gap may be too small or
too large. Points have been bent and are not
in the correct location to the latch. If you’re
using a 6 volt battery it needs to be fully
charged to 6.3 volts or higher.

TubsWell, I thought I figured it out but after what I found, I don’t know.
First run this evening I ran it without changing anything. Started after 10 or so flips, often not having enough power after first flip, and started running ccw. But after a few tries I got it running. It did t run too great, missing at low speed
Second run found that the points were 0.011, so I set it to 0.008. Started first flip and ran pretty good.
I ran it back to the dock, and took the flywheel off to check on things, and to see if the spring was bent. Put it together, and went for another run but it wouldn’t start. Popped and tried to run ccw when I didn’t want it to, so I swapped the battery terminals from + to – and – to + , to + to + and – to -.
Amazing it ran great and started first flip.
I looked back on my videos from the 1st and 2nd run. On 1st, opposite wiring, a on 2nd, normal wiring. Whether or not setting point gap did anything, I do not know for sure but I assume it does.
I plan on bending the spring so the two parts don’t touch when resting ( as I learned from Chris scratch).
I don’t know why the polarity changed anything, as it was my understanding that it shouldn’t. Either way I hope to figure out why it is acting weird.

He is the man when it comes to the Eltos.
For what it may be worth I’ll offer what I believe your issue may be.
What I suspect is that your points are vibrating and making contact
when the shouldn’t. The crack in your timer case and gas tank
demonstrate how much these motors do vibrate.
The first thing I look for as far as the points is some tension against
the latch. If there is none or the points aren’t touching the latch at all
the points and the latch could be moving when the motor is running
causing the points to close when the shouldn’t.
In your picture it looks like the points may not be touching the latch?
.

Then I also want to have tension where the two springs come
together for the same reason. If there isn’t any tension or it is
floating free not making contact when it should is possible as well.
If I find that there isn’t any tension or the springs aren’t touching at
all, I slide a wall paper knife in between them and wiggle it a little
bit to get the tension back.
.

Then I loosen the 2 screws and set the gap.
He has had way more of these than I have, or ever will have, so what
he suggests must work for him. Use you best judgment.

August 27, 2023 at 9:57 pm #279862The 2 contacts should never touch each other unless the timer is being actuated (clicked). If they are seen touching each other, your battery will soon be dead.
The contact that moves should be held away from touching the fixed contact .008″ by the long strip that has a hook on the end. The hooked end of this backer strip should always be touching the movable contacts’ metal strip at the end of its’ hook except when the timer is actuating (clicking).
The movable contact should touch the fixed contact only when you manually move the backer strip towards the fixed contact, or the hammer hits the backer strip when clicking the timer. This clicking movement of the hammer is fast and nearly invisible.
Points should be clean. Points are supposed to be adjusted by using shims under the head of the fixed contact but loosening screws to cheat works also.
