EN500 works only on one cylinder

I'll try to swap coils (if it will be possible) in Sunday. But last time issue appeared after two weeks without starting engine - usually I do this more often but had a lot of work and studies at the weekend. So it can take more time to make a proper diagnosis.

Sorry but I have difficulties to understand what do You mean.

Lets try this again. If you swap the Coils and the problem is on the other cylinder then your problem is in the coil. But by doing this it will only test back to your coil. If the same problem is still happening then you either have a problem on back in your ignition box or in the wires from the box to the coil.

The possibility of it being carburetor issue is still on the table. I just like ruling out the easy things first.

Got it
I'll check this out.
Thank You.

I would resist "swapping things around" without troubleshooting first.
There is always the possibility of introducing a new problem when one swaps needlessly and then the real tail chasing begins.

You can always make a tester. I had a homemade one for years and it served me well. A couple of eyebolts threaded into two right angle brackets fastened to a piece of wood, some HT spark lead, a ground alligator clip with short wire and you are set.

Then you can compare spark side to side. One side, you can open the gap up to, say, 1/4" and get a nice spark, then the other side might look weak and yellow or not fire at all. Then, bingo, you are on to something. If both sides look the same, (good) then you can put the ignition system in the good column.

White smoke usually means flooding.

Good point. I never thought about making one. I was just trying to offer a solution without purchasing anything. He sounded like he did not want to have to buy anything. The way I see it is If i have to buy/make a tool then I will have it for next time.

I can buy only tester similar to this one: Link. It's available in my country. But im not sure if with that kind of tester I'll be able to check quality of spark.
I'm almost sure the white smoke appears only when engine works on one cylinder.

That particular tool cannot vary the ignition system load, so in your case, it will not do the job. Sorry.

This is a quick, down and dirty AutoCAD sketch of what I understand sfair to be saying to make. sfair can confirm if the details are correct.

Yes! Make one end moveable and you are in business.
I made one eyebolt end flat and the other pointed about the size of a sparkplug center electrode.
That drawing is far prettier than the unit I made years ago!

Thanks. Here is an updated one. It is easy when you have the software made for design work.



*EDIT*
Might want to turn the angle brackets the other direction so the bottom is pointing away from the bolt (electrode). Don't need spark jumping there instead of the bolt. Might interfere with the operation.
