Oh well, I had a feeling something would come back  on me.  Last week, when the new buyer and I were test flying the engine  gave out a few Tick sounds like a fouled plug.  I changed the plugs before  delivery today and he made a successful 100 mile flight with no problems.   When he descended from 4500' at his location the Tick's started to come  back.  Assuming this is another fouled plug, what could be causing this on  such a short time?  I've never experienced this situation except for one  other time when it was for sure a fouled plug.  Any ideas?

Don,



You are supposed to have today off!  Congrats on .....

no, I can't say it.  Still sorry your plane is gone. 

Selfish, I know.



Normally a rich running or oil burning engine fouls

the plugs, but on 2 cycles, other ignition problems

are more common than on 4 cycle engines.  I think that

since you have oil in the gas, the 2 cycle engine are

designed to be better able to handle some fouling and

that leaves the other ignition problems a bit more

likely, by percentage, than on a 4 cycle.  At least

that has been my experience.



Plug gap?  Plug color?  All OK?



So have him check the timing and spark plug wires too.

 Make sure a good connection is there and no arcing

from a wire to some ground.  If he has a timing light,

check each plug wire when it is running to see where

the miss is.  A little harder to check for weak

ingition, but that may do it too.



The usual suspects I am afraid.  But you and I may be

the only ones here, so thought I would at least say

"Hello"

Don, my engine is a 503 Rotax but has the same carbs as yours.  When I reduce throttle to the mid range the needle controls the mixture.  I have the arctic sparrow adjustable needles and richen a turn or two to keep the EGT's down when I descend with the throttle in the mid range.  When it starts to get a little too rich the engine "ticks" (four strokes).



It took me a while to figure out what was causing this sound.  It could be a rich mid range (needle adjustment) in his carbs???

Could this ticking sound be the sound of the exhaust pipes cooling  

off due to the rich mixture?

The "Ticking" I was referring to is the very eary stages of a 2 cycle engine beginning to 4 cycle because it is too rich...I think.  It is not missing every other stroke yet but once every second or two, or three  I confirmed by leaning the needles one turn and the "Ticking" stopped.  This was during my first two flights so any unususal sounds caught my immediate attention.

Tom,

    I will work toward this direction of thought.  I'll also rephrase the 

"Ticking".  The tick is in conjunctions with an engine miss.  It was very 

intermittent and not present on the ground at idle or taxi.  Rather than a 

tick it was a slight bump like an engine miss.  A bit hard to explain. 

Today it occurred during his long decent from over 4000'  I assume he was 

throttled back but the mixture was probably on the rich side.

I called Jerry  at Green sky about something very similar and he described it to me this  way. Don't  worry about it.    between the way  the  muffler is chopped ,the motor mounts , jetting, it just sets up a  vibration at a certain RPM  that makes it feel that way.   sometimes I think I feel like the  rutter   is being hit buy  something . I just don't fly it  in that configuration.the cdi  ignition ether works or it don't. ether way you need to cut the cord with this  guy man.  it is his plane now  let him join the list and make the  call's.     mal

Don

  I try to never pull the power clear back till short short final. This way 

I can keep the egt above 1000 to 1100 till then. Is this new owner 

experienced with two stroke flying? Were you burning 100LL?

What were the EGT temps when it was makeing the tick?  My guess is that they 

were on the low side.  It sounds to me like the midrange is to rich.  I'm 

not an expert but I have been flying these two strokes for about 7 years in 

various different UL/airplanes and have heard the same noise (miss) when I 

got to rich.   Just my two cents worth.  Thanks

The spark plug caps can go bad. And there has been warnings about using  resistor caps with resistor plugs.

I don't understand the sound, but what altitude is your plane at now Don?

Is that why it is rich?

This isn't necessarily a sound.  It isn't necessarily a feeling.  Have you 

ever gone down the highway in you car and have the engine miss?  It's all a 

bit of a sound, jerk, feeling, noise????.  In other words, how on earth do 

you describe an engine miss????

    The altitude is at the same altitude it was when it left my home field 

+/- 100'
