First time working on multiple carbs on the Trashboat

[sparkfly88]

Set to 23mm from the highest point of the float.

This look right now?

[DGXSER]

Yes, but you may want to drop that tang that bumps the float post so the float can not drop quite so far. They tend to bind up if you let them drop to far.

Alright.... So.....

When it first started up, it skyrockets. When it warmed up, it was pretty nice.

Later as it warmed more, it got a little rough.
So I wondered...

I pulled number 1 plug wire while it putted along. No change. At all. Plug wire would put weak sparks against block when running.

Number 2 will kill the engine when pulled. Same with number 3.

Number 4 zapped me when I touched it and that ended the test because the engine wouldn't stay idled and I killed the battery trying to keep it idling.


So when I get the battery charged up, I'll check number 4 plug wire.


But. It cruises with no load now. It doesn't like to. And it's kinda rough. But it's better than nothing at this point. I'll take a video next time I get it running and I pull the wires

Sounds like you are running on #2&3, with 1&4 not doing much.
The left hand coil is the 1&4 coil, so check the resistance through the primary and secondary windings. You should get the same spark intensity through both plugs when the coil fires. If you don't, look for leakage in the high tension wires to ground, defective plug caps and/or resister in the cap, fouled center electrode of plug, wrong gap in plug, etc.

I wonder....

I remember posting that I bought the coils from mike's Xs.... But... It appears the post and opinions about Em are gone... Where'd they go....?

The site was moved to a new server and a weeks worth of posts have bit the dust.

Well it's better that reason than what I thought happened. On other forums I have seen posts deleted because of bad product reviews n such.

Well, tomorrow I get some packages in the mail, and the coils should be one of them.
I haven't touched the bike in a week and I'm getting anxious to make this darn thing run like I know it can.

Right now I feel as though I went backwards, it at least ran before I changed out carb internals and such.

Now it's being temperamental and I gotta figure out why.

Just a heads up, I've seen those MikesXS coils burn up if you are running the bike and testing for a dead cylinder by pulling one of the plug wires off. Make sure both plug wires are connected when running and you should be fine with them. GL.

[sparkfly88]

I remember reading about the failures on the website thanks for the extra heads up though.


on the walk through he used 8 millimeter wire, is that what would be used for it, or he just used what he had to make it work?

[bikerphil]

You can use either 7 or 8 MM wires, shouldn't matter.

[sparkfly88]

Thanks for the quick reply. I'm planning in hitting the auto store in a bit to go get Em.

I saw the 8 mm fit a bit tight on the walk through. So maybe 7mm will work better.. I'll bring a coil to test fit some wires.

[sparkfly88]

I'm pretty electronically retarded..... Plus I really don't wanna fry these things...

Which primaries are positive and negative?

The coils are marked that way, and I really don't wanna fudge up


Also. Never messed with these kinda coils.... I suppose I just push the wires into them and make sure they bottom out, making the spear tip in the coil poke into the wire making the connection?

[crazy steve]

If the primary connections are marked, connect the red/white wire to +, the orange/grey to -......

[sparkfly88]

Thanks! Man that was fast.

I'm in the process of figuring out making the coils and wires. Lol.

[sparkfly88]

ALRIGHTY THEN. I seem to have run into a problem.

Seems faulty mass production has struck.

I simply went to remove the connection to heat shrink it and the entire damn plug came with it.

I'm livid. OH AND GUESS WHAT. The other connection is getting ready to do the same thing, I went to slide the connection off and I saw the entire thing move instead.
