Ok thanks goober, I was able to fix the switch with your tutorial, but alas, still no spark.  Gonna get a new cudi box and spark plug

Ok thanks goober, I didn’t know if that would come apart without breaking.. I’ll give it a whirl tonight 

I did that, except the kill button doesn’t switch on off, I suppose because I don’t use it... can it be bypassed easily without messing up anything?

I don’t see where it unplugs at

I was just going by the manual, which I didn’t see mention that.. where would it unplug

No, just had it on run

I was going by what this says, there is continuity when it says there should not be

So... upon further testing I seem to have continuity (when I should have none)between bl/w and g/w for the kill switch. I never use it anyway, is it difficult to bypass?

I knew I was doing something wrong, I didn’t see the k on the ohms standard

I was following that section of the manual. The meter is to the lowest setting and I read .5 between the green terminal in the black terminal, but I cannot get a reading between the green terminal and the end of the wire, I am definitely contacting the wire out on the end… I even had an electricApprentice try it and he got the same result

it is a 350a

So, I was riding on a very hot and humid day, and the ol girl (87 fourtrax 350) suddenly stopped running.  I got it pulled home, discovered no spark. Couldn’t get an ohm reading on the secondary coil. Ordered a new one off eBay, brand new genuine Honda... hooked it up still no spark, so I took it off and brought it to the multimeter, and I’m getting out of  range reading on the primary coil but no reading on the secondary as pictured (exactly like the old coil).  Am I doing something wrong here? 

Welcome from central mn!  I can relate as my first atv was a 110 3wheeler, good times and several injuries!

I don’t think I ever introduced myself.  I’m keeping an ol 87 350 running with help from the forum. I’m located in central Minnesota.  I don’t have much for great places to ride around here, but I do use it for hunting/fishing.. 

For work I do rural mail delivery, and I still do part time construction (was full time almost 20 years).  
I have a fiancé and 6 year old daughter, and a couple dogs..
what else is there to say, besides SKOL VIKES!!! (I see all you aints fans lol)

Where are you located Wampus?  I've got some rear fenders that are rough, but more than what you have there.  Don't want to ship them, but if you're anywhere close you can have one.

I’m in central mn

Got mine running again! Thanks to the help from this forum.... It might not be much to look at but it does what I need it to do

Well you all inspired me to do a more thorough cleaning (I noticed that one of the gaskets had been silicone at one time) and got the parts in the correct order (I am certain they were not correct the first time I took it apart).  The only thing I skimmed on is I  put it together without the baffle, because I never had one and I couldn’t seem to find a replacement.  I got it together, and the ol girl runs good again!

thank you all

Well I live up in the land of salt and snow (mn), rusty vehicles are a way of life. I like kroil, but if it’s really bad, I use an old trick my uncle taught me....  heat it up with a torch, then hit it with nozzle wax from the welder, penetrates better than any cold oil

I searched eBay for a replacement baffle, to no avail....😕

That’s not an oring on your main jet is it?

Well, there was one there when I took it apart the first time lol

Two other things

the main jet is removed by pushing down on it (use the butt end of a screwdriver) from the throttle piston bore

 

did your carb have a good passage plug?

see the carb on the left? It’s missing one—you can see it in the carb gasket pack.

 

Yes I do have the old passage plug, my kit did not come with a new one. 
I took a picture pre-disassembly, don’t laugh too hard.. I did put it together like this, but I did not have a manual and I copied the way it was as closely as I could… I’m obviously not the first person to have been in there. 
I seem to be missing the “baffle”, I do not have an old or new one… How important do you think that part is?

FOR CRYING OUT LOUD THERES A SERVICE MANUAL? Sorry for yelling but I looked through all the old posts trying not to ask for help when the information is available 🤦🏼‍♂️🤦🏼‍♂️ 
thank you got the very thorough answers, I’ll get it together later today

Well here I go again...  

I took apart the carb to clean it, and some of the gaskets stretched, so I ordered a shindy kit. Now it’s been over a week, and I’m not certain where; the Orings, the one little washer, and that one little round seal that isn’t an oring, goes..😬

Rural mail delivery, part time construction.

It runs better, but still doesn’t idle correctly, I may have to put another carb kit in..

That wire just makes the neutral light come on to start it, also known as my “anti theft wire”

Does this look a little better?  
I do not have the original wiring, thus the ground  to motor..
