I have a Lightspeed ignition on

 an O-360

                            Lightspeed says it has to be timed by using

a timing light from behind the engine shining forward onto

the flywheel.

                     The problem is that the front baffle is in the way.

Do I have to remove the baffle or did someone find a better way?

        The baffle is difficult to remove especialy with the prop and

flywheel attached!!

I don't know why the timing light has to be behind the engine.  Just 

hold it up where it's flash can be seen on the back of the flywheel.  

Obviously, more caution is required the closer you get to that spinning 

prop.  Worked for me.

Are you suggesting that you are timing your engine using a timing light and 

while running?  If so, you're nuts.

It'd be pretty stupid to try to get a timing light to work with the  

engine stopped.



Nobody would try to adjust the timing with the engine running, you  

simply check it.   If it's not quite right then stop the engine, make  

an adjustment and retry.  This is the suggested method in the  

Lightspeed documentation.



You don't stand any closer to the prop than the firewall.  If you  

don't feel comfortable doing that then don't do it, but I assure you  

that I am not nuts.

The baffles should not be hard to remove. I just took mine off with the 

prop and fly wheel in place, they came right off.

What's nuts about it. I do it all the time. I've also located induction leaks with a can of starting fluid with the engine at idle. I know some have used a vacuum and soap solution but the other way is easier and quicker in my opinion. If you have a Plasma  system and ever have a backfire in the induction system with the throttle closed, you'll probably be looking for a blown gasket. You know the prop is there, just stay away from it. Timing the mags using a timing light is much more accurate. It's true Dynamic timing!!! Also the light speed is best timed with a timing light per the manual. You might be surprised what you see and here standing right beside your engine, cowling off and engine running.

I mounted a pointer on the forward side of the front baffle. The pointer can 

be set at the case center line very close to the back of the flywheel. It 

can be swung away, lock screwed and safety wired when not in use.

This provides an easy and accurate way to set the timing. Reducces 

parallelex problems. The back of the flywheel has it's timing mark 

highlighted so that when the pointer and the mark meet the timing is right.



I can make pictures available.

Charles,

  I'm with Phil on this. Using a timing light is the ultimate for timing accuracy. I generally sit on the right wing while checking the timing with the engine running. This works well when done in low light, such as at dusk. As Phil mentions, adjustments are made with the engine off.

Brian,

  Using a flammable fluid to locate induction leaks is a time honored technique among auto mechanics. However, I would like to suggest that aerosol carburetor cleaner or aerosol throttle body cleaner is a better choice. The ether in starting fluid is HIGHLY volatile and poses the threat of detonation. Carb and throttle body cleaners are safer.

I'm curious, has anyone actually found that the Lightspeed timing was

off, and if so, did you discover any reason for the inaccuracy?  I have

dual Lightspeeds with the crank trigger pickups and I admit I did not

check the timing with a light.  I did verify that the magnets were

installed in the flywheel and the pickup bracket was correctly aligned

per Lightspeed instructions.  After 100 hrs in flight, no problems with

anything.  But that doesn't guarantee the timing is right so maybe I need

to check it??

 I have the same dual trigger system and did check the timing.  No  adjustment was necessary.  I now have 178 hours and it's worked flawlessly  the entire time.  Plus, it sure makes starting a hot fuel injected Lycoming  a snap.

I have the hall effect sensor on mine which is adjustable so it makes 

sense for me to check it on occasion.

Phil, I have the halls effect sensor also and just got it adjusted and 

started my engine for the first time today. Did you check yours with the 

auto strobe light? If so how did you do it? Do you have a key switch? Do 

you know how the wires are hooked up on the back of it? It appear that 

my mag is not grounded with the key off.

That right there just rationalized the flywheel magnet setup...

It gets adjusted just like the mag does, when you check your mag 

adjustment you check the hall effect sensor. It should not need to be 

adjusted any more than the mag. From the discussion it appear that once 

it is adjusted correctly it pretty much stays there. I got mine adjusted 

today and the engine finally got started it seem to be running great. 

Another month or two and it should be flying

I have had a plasma lll system on my RV6A Lyc. 0320 for two years now. I  have set the timing on both the mag., which is on the left and plasma on the  right. with a strobe light. the system has worked great. But I have had one  problem with the engine since I installed the plasma III. The CHT runs quite a  bit higher when running on both mag & plasma system. Before I installed the  plasma my CHTs would never get over 400 in a climb, now if I run with both on,  my CHTs will go well over 425. By switching off the mag. and using only the  plasma the CHTs stay well below 400. Does anyone else have this happen?

 That is to be expected.  The EI burns mo better so the CHT goes up.

 Increase the cowl exit area so you get better cooling.

Well that seems to make very good since, but the CHTs go down when I run  with EI only.

When you run on only one spark plug, it slows the rate of burning, having the same effect as retarding the timing. This causes the CHT to be lower, and the EGT to be higher (the latter because some of the fuel is still burning when the exhaust valve opens). 

 

 You should see approximately the same effect if you run on either one, especially at lower altitudes (before the Lightspeed unit starts advancing the timing). If not, you should check the timing on both.

 

 When you have dual Lightspeeds, they are connected together. If one fails, or is switched off, the other will advance the timing to compensate for the change in the rate of burn.

 

 You can get the same effect by changing the timing on both. That is, if the timing is over advanced (you haven't given us all the parameters of your engine and settings), if you retard both, your CHTs will run a little cooler, and your EGTs a little higher.
