magneeders mags.

[Tom Deere]

Does anyone have any experience with Super Spark mags from Magneeders? I am thinking of putting one on my 36' A. It says on his website they spark on the compression stroke. Would I have to do anything special or could I just line up the new on in the same positon and the old one? Do they really help make starting easier? Any help would be appreciated. Tom

WELL... I would DARNED WELL HOPE they spark on the compression stroke, or at least at the end of it! Wouldn't be much good, at all, if they didn't!

Tom, I have NO expreience with Magneeders, HOWEVER, I can tell ya for a fact a good strong hot start/impulse spark can greatly improve hand start performance and I believe probably more then any other single thing provided carburetion n compression are at least decent.

As far as their firing on the Compression Stroke (I agree with Bob they pretty darn sure better lol) Im guessing they fire ONLY on the Compression Stroke as reduction drive gear mags do unlike the Wico C and X that fire on BOTH the Compression and Exhaust. However that dont really hurt (firing on BOTH) and dont see how it affects hand starting cuz its still obviously the spark on the compression thats important DUH

The weak link in hand start plug firing is the fact that the impulse spring wind n trip assembly and especially the springs tension and stored energy is whats necessary and critical cuz as the rotor turns slower past the coil the weaker the spark. That (spring induced rotor speed) coupled with the coil, the rotors magnetic field strength and the irons magnetic properties determines how much saprk energy can be produced when hand cranking and those can alllllllllll be enhanced and improved which I assume?? the Magneeders hot mag incorporates.

The absolute greatest improvement I experienced in my hand start B was AFTER I had Glen in Texas "soup up" my Mag with the hot coil and correct matching condensor and improved spring assembly. I usually rebuilt my own and that was fine up to a point, but I lacked the equipment n resources (regarding the mechanical and spring n impulse etc aspects) to as good of a job as he can, Electrical stuff is my specialty NOT mechanical n those darn springs n such lol.

Get a Hot Mag, you wont regret it......is my best good faith advice

Darn Bob, Mean to tell me they wont work if they only fire on the exhaust stroke huh lol

Take care,

I asked the guy there at magneeders if a hot mag would help me gain power . He told me if ur motor is not modified for pulling ,running high compression , it probably wont help a parade tractor much. He rebuilt my old wico x to factory specs and my tractor runs much better now.

John,
It's an emissions control thing, you didn't get the service bulletin?
If a fire ball doesn't rise at least 36" above the stack after 10 cranks and a no start, you'll get a visit from the un-burn't hydrocarbon tree huggers.

All that i can say is that I love mine yes they are spendy. The tractor starts better and makes more power. I have been playing around with an lp distributor. They do basicaly the same thing fire only on compression. I will say the tractor definantly starts better on the mag. Just my experience hope this helps.

The Tree Huggers didnt catch him buttttttt I knew this "Dude" once who took an old fridge to the local recycling joint and they called 911 n came runnin n kickin n screamin out in white Haz Mat suits with a Swat Team n told him he had to get the freon properly sucked out or we would all die n the planet self destruct before next Wednesday soooooooooooo this same "dude" goes back to his farm n takes his pliers n breaks the freon tube n it alllllll runs out n escpaes buttttttttttttt bout a week later it got hotter n a hammered H _ _ _ soooooooooooo them tree huggers just might be on to something??? Who was that "dude" I wonder???????????

John t i know in theory that a mag is firing or will fire hotter than a distributer . Do you know how much that difference would be ? Would a distributer running a hot coil be equal to a straight mag ?

 

[Tom Deere]

Thanks all for the advice. John T, I didn't see Glenn in Tx post for a long time, is he ok and still doing his thing? I talked to him a year ago about my 'D'. I am having trouble finding his email and phone. Oh yea, the paint job on your 'B' looks far better than the paint on my '04 truck, won't tell you the brand, too embarassed! LOL! -Tom

Two Cylinder, Id say the opposite, generally speaking a garden variety Mag produces LESS spark gap energy then a battery powered coil ignition buttttttt thats a pretty broad statement n theres lots of variables. For instance, the faster the mag rotates the more energy it produces while the coil ignition (provided sufficient dwell time which is NOT a problem on low RPM tractors) can produce the same energy from idle to wide open. PLUS it has the major advanatge of a variable timing spark advance curve versus the mags ONLY start and run timing. The low output energy of a relatively slow turning mag is why its so critical the points n condendsor etc allllllll be in good condition yet the higher energy coil ignition can be more forgiving like burned or mis gapped points yet stilllllll yield a decent spark.

To answer your question, its my general opinion a distributor with a stock coil (original ignition system) will probably (no data to back this up, however) still out perfrom a mag with even the HOT coil.

A mag with the so called "hot coil" likely produces more spark energy then with a stock coil. I would figure the so called Super Mags for pulling use much higher efficient n quality coils that can produce higher voltages necessary for higher compression,,,,,,have rotors with greater magnetic strength,,,,,,,have better magnetic property n iron so that indeed produce more spark energy plus can fire at higher voltage if its necessary (like real high compression).

I guess one will have to admit a mag in good shape can outperform a weak n worn out coil ignition but thats really a non issue here.

Heres some Mag advantages though: Say a coil ignition has a weak battery and/or a bad starter which is reallyyyyyyyy dragging the battery voltage down, its starting spark can be pretty weak (cold starts when you need it the most) where a decent mags start impulse spark would likley be stronger...... no battery required to produce a spark whatsoever. However to help cold starts the 6 volt coil and a ballast by pass on 12 volt tractors works quite well to reduce the disadvantage above.

To Mag or NOT to Mag, the choice is yours

I guess thats why the drag race boys run mags stead of distributors,dont wanna make tooo much hp. Later Hoss

As ive had a couple folks tell me that mags are hotter than dist. . As hoss stated they run mags in top fuel dragsters. As i understand a mag is sending a more powerful current since the coil is right there. But im no expert and u sound like u know more than me on this subject john t .

 

[John T]

SUREEEEEE They can run an expensive high energy Magneto in a race engine and aircraft engines and Hoover/Boulder Dam uses a sort of "Magneto" to generate thousands of killowatts of electricity and thousands times more energy then an old tractors coil ignition system

BUTTTTTTTTTTTTTTTTTTTTTTT THATS NOT THE SAME MAGS USED IN OLD TRACTORS

You gotta compare apples to apples here guys

An old low energy Wico tractor Mag IS NOT THE SAME as n expensive high energy race car or expensive airdraft mag or the dynamo generators used at Hoover/Boulder Dam !!!!!!!!!!!!!

Remember, the general proposition is that a stock battery powered coil ignition system produces more spark gap energy then the stock garden variety magneto NO ONE CLAIMS OR BELIEVES AN OLD TRACTOR IGNITION (Mag or coil) PRODUCES MORE ENERGY THEN AN EXPENSIVE HIGH ENERGY RACE CAR OR AIRCRAFT MAG, YOU GOTTA COMPARE AN OLD COIL IGNITION VERSUS A LIKEWISE OLD MAGNETO FOR A TRUE COMPARISON.

Regarding a mag sending a "more powerful" current since the coil is right there versus it being say located even a foot outside a distributor, that has nuttin to do with the current that can be generated. A coil is a passive inductive energy storage device that stores energy in a magnetic field when current passes through its primary low voltage winding cuz a voltage difference is impressed across it. In the magneto the primary voltage is produced by the passage of the magnetic rotor past the coil (induced voltage) while in a battery powered coil ignition its the battery that supplies the voltage and a big honkin battery being kept charged by a generator can supply plenty as compared to that limited in a magneto by the pasage of a magnet past a coil of wire.

Sorry, but its IMPOSSIBLE to explain in a paragraph what takes years to learn and there are entire libraries devoted to how DC generators and magnetos and Kettering coil ignition systems work, you just gotta go with the flow and its your tractor and whatever ignition, a mag or a Coil is you choice and I will do my honest best to help you fine gents with your problems in this great hobby we all love n share.

Best wishes, hope this helps, yall take care now.
