All you did was supply 12V and ground to each of the coil's terminals. Series, parallel, whatever.....makes no difference as far as I know. Each gets 12V and ground on the correct terminal. The reluctor wheel's magnet on the crankshaft triggers a Hall effect transistor in the "ignition module"...

Some but not all...

Boy...that really cleared that up....so is a Kawasaki and tons of other two cylinder engines. Nothing special.🙄

So...on an Onan two cylinder opposed, is there but one coil for both since both would fire at the same time. The only way for plugs to be in series would be on the opposed cylinder models. But looking at the diagram from post 62 shows the outputs to be in parallel, not series. Any V...

Try it on an electric fence sometime. Light. Light. Light.......

As was stated earlier, better to remove plug, insert into plug cap, and ground the plug to discharge energy via spark.

See post #21. As I mention there, it's not entirely intuitive as most forum software just has a CANCEL button right next to the POST REPLY that takes care of the issue. The solution is already posted to the Community section. Cheers!

You made me question my advice to just pull the cap....see post #57. Thanks!

Grab the cap and pull it off...won't get shocked unless you want to stick your finger in the end...🤔 The voltage isn't enough to each around the insulated cap. Many of the really old cables just had a bare metal clip that attached to the plug. If you have that I'd be surprised. However, in...

How many hours on this engine.....

Now is the time to take the belt to a shop that has a belt measuring stick and see if it really is 95.5 inches.

Like being a parts cannon, eh? Isolate then buy. Don't just throw crap at it till you know what it is....

Engine Options: Kawasaki, Kohler & Briggs...never offered with a Yamaha.

Do this.....get a sheet and a flashlight.....sit under the sheet on a solid floor because those springs will launch to God knows where sometimes. I "lost" one spring but knew the last thing it hit was metal after bouncing off the ceiling and eventually found it in the top of my tool chest. Work...

Ignore the bad spark tester, good spark tester argument for the moment. While running pull the plug cap off one plug and note how it runs. Replace it and pull the other one. If there is a coil failing one of the two will cause a really rough running, skipping engine and the other might not (rare...

Posted a question about how you dismiss a REPLY "quoted text" box if you change your mind and decide not to reply..... This is solved.....If you decide to not reply after all you must first POST the reply, even if blank, and then use the DELETE function of the POSTED reply to kill the...

No, I know you're not...this software is counter intuitive to any other I've encountered. When you hit REPLY to a post, does it not bring up the greyed out original post as "quoted text" and allow you to "associate" your reply with that? Yes it does. But if you change your mind there is no way...

Try it. Then try to dismiss the reply page. What you get is the quoted text box without any associated reply. I guess you've never changed your mind.....lucky you.

It's solved. A counter intuitive way to do things....when you hit REPLY then change your mind you have to POST REPLY anyway. There is no other option. Then the posted reply has the DELETE option that kills the post. My guess is the programmer already had the post number (in the upper right of...

Yes....you can do that but the original quoted message still remains on the screen and cannot be dismissed. If I wanted to I can build a huge chain of REPLY blocks, each with its own reply/message number and there's no way to dismiss any of them. Not that I would do that but it's an interesting...

You just repeated everything I said...

And this should be Post #5 being checked on a Linux machine......when I looked at this post with the prior text in it, and again after DELETE DRAFT was used the draft text was gone but the only selection available was to hit REPLY as there is no option to CANCEL.....Quite confusing.

Crap....being stupid has its costs. Thanks! Never once thought the save would have two options. However....just tried and the draft goes not go away and the REPLY block just sits there and doesn't close irregardless of DRAFT deletion. There should be a software option icon that allows the...

I'll bet there's a way to do this but is sure isn't obvious. When you select REPLY and the quoted message comes up with your space below it to reply....how the hell do you cancel the REPLY action. There is zero cancellation selection anywhere so now you're stuck with a quote with no reply just...

Methanol burns about two times slower and only has 9500btu/lb compared to 18,400btu per pound for gasoline. My guess is these were not blown or turbocharged so there is no way you could get the power you claim unless you burned 3 times the amount of methanol compared to gasoline. And...the...

Most don't know about this mix.....they usually thing it's just some backwoods retard that invented it. They always mention that they don't "mix" (immiscible is the proper term)....so just shake it up so that both materials are present on application. The one caution is acetone will burn at much...

Not my sarcasm...just a quote. https://www.lawnmowerforum.com/threads/briggs-stratton-ohv-plastic-engine-no-compression.79809/post-514532

Automotive repair or engine rebuilder....most straight machinists don't.

These are mower engines not the space shuttle.

Whatever.

Not the whole industry....just the gullible part of the industry. Let's take Permatex 80037 as an example. This material is your silicon carbide in 4 mixed grits... 120, 150, 180, and 220. Ostensibly the grit size decreases as the paste is ground between the face and the seat...or so Permatex...

But then you still have the seat...🤔. Agreed that not many have the stones or the tools to grind seats and/or valves....or the skill. It can be a pretty big investment and for a one time use it's better to take the parts to someone in the business of valvetrain restoration. New valves and...

Lapping does not increase compression. Will not remove pits, not used for removing carbon, and has zero effect on performance. There are tons of marketing ads pushing this crap and it's all a lie. The only value of lapping is to verify correct contact location of the seat on the valve and the...

Precisely the behavior of my engine. Thought at first it was fuel pump related but no....ignition. Pulling cylinder 1 plug cap resulted in a very rough running engine. Pulling the #2 however engine ran smoothly. When I say smoothly that means the ignition was consistent with #1 coil but still...

As it so happens I just had to replace both coils at 480 hours. Yes they do fail and it not ucommon for them to fail . The post below explains why. The transistor managed coils are not all that robust given the hostile environment they live in ,primarily heat related...

I would pay to watch him do that....🤔

You ought to watch some YouTube videos of Pakistanis rebuilding engines.

The fuse kits from Amazon and others are crap. There are tests of fuses rated at a specific amperage that continue to operate at 400% above stated rating. All are Chinee made.

Just replaced both of mine at 480 hours on the originals. The result was dramatic.

Yes...there are two transistors in each coil and they can and do fail. Every revolution of the engine creates a spark. At 3300RPM that's 55 sparks a second. The high heat environment doesn't bode well for long life.

This is not a plea for help as it has been fixed, just a heads up on cause and effect. The ignition coils on these engines are different from the #1 and #2 side with different part numbers and have a pair of transistors inside the units that control primary winding charging and field collapse...

Lapping just makes the seat and valve shiney.

Exactly.

Why does a compression release exist? For the weak human pulling the cord. No engine equipped with a starter should ever require a compression release. And no amount of adjustment of the valves will fix a worn compression release cam lobe. Drain your oil and look for sparklies. May be worse...

Kawasaki makes their small engines in MO and NE. One of the first to do so. Toyota, Subaru, Nissan and Honda followed suit. Not everything is made overseas. Tariffs can be avoided. Buy American. Just because it sounds foreign doesn't mean it's not built here by American labor and materials. Some...

Japan's Tanaka when they were still in business. The only manufacturer with a 7 year residential warranty, 3 year commercial. Light, simple, trivial to work on. Still believed the customer was smart enough to make their own carb adjustments.
