For gas powered engines we've run the stock Kohler coils and made power up to 10,000 rpm so I don't know whats up.  I think its probably because your running the wrong type of coils, you need to use the coils off of the 18hp Kohler Commnad, the ones with the rectangular side legs, not the ones with a cut out on them.  We build our $2000 engine special for lawn mower racers and pullers all the time and use those coils with no problems at all, so as far as the Kohler coils don't work your all wet, but some types don't.  I wouldn't condemn a product that works if you don't know all the facts about the various types under that name.

JE may stop making JR drag racing pistons that strange, but what in the world does that have to do with us.  All of our pistons are custom made either from JE or Diamond for our application, we don't try to shoehorn in junk that it isn't made for it because we have it setting on the shelf.

Tom, Since the wheel I have on my Intek twin will work on a kohler twin with an update, What is the chance that the 28/31 briggs single wheels will be the same on a Kohler Single?

stahlwerks: the coil change has to do with two things.  1. It is what we were told was desired, and 2. we wanted to use what we already knew would work with our existing magnet configuration.  As a side note, the ability to utilize the 6611 body as a base means we don't have to create a "special" part for specific engine that may not represent a very large market.  This makes the part less expensive.

If you have to change the coils from what comes stock anyway, why does it matter which coil is chosen?  The Vanguard coils are inexpensive and proven with our flywheels.

As far a shoe-horning junk sitting on our shelves...we are designing the rod and likely making the bearing as well, so we can make it to whatever specs we want.  Wiseco stocks a great deal of larger pistons for motorcycles and such and these pistons are less expensive than custom stuff.  The pistons are the same as what you would get if you had custom wrist-pin holes and such, so we aren't shoe-horning junk, but rather we are adapting an existing proven setup with a product where we can choose the configuration.

rceagle1a: I've never seen a Kohler single...so I can't answer your question. sorry.

Command vtwin. 18-30hp all the same flywheel. And most all the other parts except a 30 has a little bit more stroke then the rest of them.

Are the rods the same in the 18-27HP?  There is an offset built into the rod at the main journal end on the 18 and we figured that offset changed as the bore size went up.
