Well the aftermarket coils are not working out very well for me.
I got 2 pairs of the AM coils, a pair that I bought last year(that were advertised as Genuine Kohler, but were not) and a pair that I ordered recently.
NONE of the 4 AM coils worked.
Fortunately I tried firing the engine before doing a complete reinstall each time I installed different coils.
I installed the pair from last year first. I had to trim a small amount of plastic from the coils to get them to fit on the coil mounting pads. Even with the trimming done, they could not be gapped the way the OEM coils are. Putting a curved .012" feeler gauge under the OEM coils would result in the gap being .012" under each pad on the coil. Doing that with the AM coils resulted in the center pad at .012" and the end pads about .015" if I spaced the end pads evenly. This did not result in the engine firing on either cylinder(w/2 new AM coils installed) and I tried playing with the gap without any success.
I then installed the second set of AM coils(they also required slight plastic trimming) and tried different gap settings, none of which provided any spark.
I was concerned that something besides the coils was causing the no spark issue, but when I reinstalled the one good OEM coil and a good(but old) OEM coil that I had replaced last year, it started and ran fine.
Fortunately I have a lift with a hoist directly over it so I was able to do all the work myself with a lot less effort than it would have been without the lift and hoist.
I now want to purchase some Genuine Kohler Coils Part # 24 584 45-S.
Has anyone purchased from OPEENGINES>COM? Good results?
Anywhere else that I can order from and be assured of getting Genuine Kohler Coils for a good price?
