I've got the Kirk "clone" coil on my 120 and it along with the electronic pointsaver made a world of difference in a good way. The clone is a "copy" of the Bosch Blue coil but there are several different versions.
I am not willing to risk the cheap or no name stuff.
Need to order one for my 312 since I lost the coil tonight.
I agree about "no-name" crap... I hate re-do's....
The Kohler stuff IS WAY OVERPRICED!
The resistor, and non resistor type coils that are imported, are good, they sell em at Orielly Auto, and the VDubb stuff comes on the same boat. If they were NO GOOD, nobody would buy them! Ford 8n, 300 six, blah, blah, blah is wayyyy cheaper!
This is what I do, buy a "supposed junk engine", and if it is junk, part it out. Put the items on a shelf, no workie, grab anotha!!!!
Fyi, high performance coils wont make any difference on a stock mota!!!:) Cheers
Yeah I agree on the Kohler stuff (especially factory Kohler parts) being over-priced, that is why I am looking elsewhere.
Yeah I have bought many "supposedly" junk machines over the years, that wound up with something stupid-minor wrong with that wound up an easy and cheap fix that would wind up serving me well for years.... that is most of what I buy haha
On the performance coils not making a difference on a stock motor, true. I learned that via many years of fixing cars...
the biggest hi-volt super duper coil won't produce any more than a stock coil has to if plugs wires cap rotor etc is all in good shape.... but has the POTENTIAL to produce more than the stock part.... proof of this can easily be seen with an engine on a scope.... run it stock, swap coil, run it again.... no difference will be seen unless the old stock coil was somehow "bad".
and no, a coil capable of producing more power than a stock one WILL NOT "burn a hole in a piston" just by itself!!!! Very old, old wive's tale.
But, since I have 2 machines here right now that need coils (a 1200 and a 129) anyway, so i gotta buy 2 coils anyways, and these are available for the same money or less than many that say "FITS Kohler".... meaning not OEM replacement... and I can get an upgrade at the same time.... then why not?
The big plus of the "clone" coil and the Bosch Blue is that they are not oil filled but filled with epoxy. As for a coil upgrade on a stock engine, everyone is entitled to their own opinion.
I remember having heard something about the advantage to those coils and the reason the "pullers" like them so well as opposed to a stock replacement, but I could not remember "why" those guys liked the Bosch Blue coils better than the stockers... the main reason I started this post was to find out just that.... I hear claims that this BERU coil is supposed to "be the same as" the Bosch unit, would like verification or denial of that, inclusing "how good" these ones are, mainly how durable they are and if they will last...
I know the wrong coil will arc your points and melt them right away, in similar fashion as if you had no condenser.
Wrong as in how? I have had that happen before but not from the wrong coil... in my case it was a fried ignition switch that allowed battery power to feed thru the coil on a magneto system which should NOT be fed power/ or a wrong application of ignition switch for the machine. I have converted magneto ignitions to battery ignition before. In that case you do need a 12V coil. You may need a different condenser, and either a different ignition switch or else a dedicated "kill" switch separate from the ignition switch/ but you can still use the same points.
