Guys, thanks all of you who answered my query about a kick back problem

with my IO-360. I should have included info about the battery and ignition

system. I don't have an electronic ignition system, just two mags, the left is

equipped with the standard impulse coupler.  I have a new Concord 25RG-XC

battery that is fully charged. When starting, I always flip on both mags.



I have recently been experiencing start problems where the engine will fire

on a cylinder or two for a few seconds, then gradually on all four. Sound like

a impulse coupler problem?

Walt,



Unless both your mags have impulse couplings then you should start your

engine with the impulse mag on and the non impulse mag OFF. Once the engine

is running, turn on the other mag.

Walt, the impulse will disengage at a couple of hundred RPM if I recall. 

 When it fires the first time or second time may be enough to get past 

that.  At that speed though, you could turn on the right mag (because 

you're starting on the left only now aren't you???) and see if it helps. 

 A good plug cleaning and leaning on the ground may help also.  What you 

might have is not enough primer so I would experiment there.  While the 

engine is cranking, give the primer a push and see if that doesn't speed 

things up a bit.

No, it sounds like the non-impulse coupled mag is firing before TDC 
	


(like it should) during starting.  The purpose of the IC is to slow the 

mag down so it fires right at TDC during the starting process.  When the 

engine is running, there is enough speed and inertia that firing at 28 

BTDC is desireable.  Duirng starting, when the engine is running so 

slowly, if the non-IC mag fires at 28 BDTC, it is likely to cause a 

kickback.



Try leaving the non-IC mag off during starting.  If you have a 

keyswitch, make sure it's wired properly to ground (turn off) the non-IC 

mag at the START position.

I'm very close to wiring my plane and would like to know how to wire the 

ignition key switch.  I have an AeroSport IO360 with one "mag", and one 

Lightspeed Electronic Ignition.  It seems that the forum is suggesting that 

I wire the key switch so that in the "start" position only the Mag is 

firing, but upon releasing the key switch from start to both, that then both 

the mag and the Lightspeed are firing.  Is this correct?

No, you want to start the engine with the EI ON and the mag OFF.

Why would you want to do this if the mag has the impulse coupling?  You 

might as well use an non IC mag for that.  Does the electronic ign have an 

option for retard timing?

All EI systems I've seen have a retard mechanism for starting. One of the

main benefits of an EI is it's supposed ease of starting.

FYI...I had an electroair ignition and had problems with Kickback, and the subsequent owner did as well...even chipped teeth on the ring gear...could have been the ignition, but not sure...I seem to remember that you started it on the EI, but didn't turn on the advance function until start, but that was 5 years ago, and am not 100% sure.
