| Subject: | Lesson Learned - 912 & spark plug gap |
--> Kolb-List message posted by: BICUM@aol.com
Hello list,
This may be repetitive and common sense stuff to most. I have been having
trouble starting the 912 lately. Initially I attributed it to not running very
much. Between the long delivery on the new prop, weather, and work - not much
flying. My 912 had always crank almost instantly. Lately it has taken a lot
of cranking and several attempts. Warm starts were even taking longer than
normal too.
I had put new plugs in at 200 hours just before the Sept flight to KH/TNK.
Started seeing small hints then. I had gapped the plugs @ .80 mm. The
maintenance manual stipulates a .70 - .80 mm. If you read further (ain't that news),
it even has a statement about reducing the gap to .5 mm if you are having
starting problems. So I decided to check the spark plugs. Reduced the gaps to
.70 mm. There ain't much difference in the gap but it sure makes a lot
difference in the start. Cranks right up just like it used to.
Less than 2 months to MV!
Thanks & be careful,

| trouble starting the 912 lately. | John Bickham
Morning John B/Gang:
Wish you had said something a little sooner.
I had that problem with a brand new 912, 10 years ago. Really
upsetting to have a brand new engine that would not fire. There were
no instructions in the new operators manuals to close up the gaps.
Was getting ready to leave for the long flight in 1994. Flew down to
Ronnie Smith's, Lucedale, MS, to see if we could trouble shoot the
problem. Once started, ran great. Just would not fire on start up.
Landed at Ronnie's. Went to lunch. When I came back, the 912 was
fixed. Hit the starter and it would fire right up. While I was at
lunch, Ronnie closed up the gap to .020".
Four years later, Lake Texoma, Texas. Bro Jim and I were ready to
head down to Dallas. 912 would not start. Pulled the plugs. Closed
the gaps to .020" and she fired right up.
Glad you got it figured out.

"Your spark plug gap problems remind me of my Yamaha mechanic days. Back
in the 70's and 80's Yamaha had some screaming 350 cc two stroke
motorcycles. (which always kicked the snot out of the Honda's, NOTE: Don
G.) They had gap and fouling problems until CDI ignition came along. What
I did was remove the original factory coils, closed my eyes and threw
those damn things as far as I could. Then I went down to my local NAPA
auto parts store and bought Delco/Remy auto coils, the best plug wires and
caps, installed it all and the spark plug problems went away. Maybe this
is something that would help out the 912????? There are some fantastic
high energy coils out there on the market for the racing world. Might be
worth investigating."
Memories of the 70's, some days I wish I was back there.

Hi Dwight/All:
I think it is a problem Rotax should work on.
We discussed this problem during the 912 School, so Rotax is aware.
When it happens to an owner that does not have the fix, it is
devastating.
I notice no difference in performance between the normal spark plug
gap of .028" and .020". So, I go ahead and set my plugs to .020 or
.025" when I replace them. What happened in Texas was errosion of the
ground wire and center electrode widened the gap until the old 912
refused to fire.

Dwight..
get ur finger outtra my side ya ole hayseed!...hehe
snip>>>>>. (which always kicked the snot out of the Honda's, NOTE: Don
G.) They had gap and foul<<<<<snip
HEck pard..I remember those days well..early 70s fer me.....My first REAL
motorcycle was a Honda 125XL..(after the 56 Cushman)..man...was it
purty....but there was absoultely NO body that couldnt outrun me of all my
buds with those 2 strokes....boy was I dissappointed, as soon as I tore it
up good.....and saved my pennies...the next dirtbike was a 250 Yamaha...YAAA
MAN....that sucker would cook!...and..."injectalube" If i remember the trade
name right.. by 73 I was outta the dirt and onto the asphalt, so I left the
2 strokes behind for 4 cylinder Hondas and ......
wait....this was supposed to be about Ignitions and plug gaps...opps...sorry
men....
Generally, there is a minimum rpm that you must crank the engine over in
which to make enough energy to jump the plug gap...so when the gap is a tad
to big...and the cranking rpms too low....she wont fire...pretty common
thing, and the first thing you need to check alot of the time....
