My 009 has way too much advance!

Ahhhhhhh!!!!!!!! Hi Alvin. Setting up an 009 at idle speeds by turning
it to its fastest idle speed is a surefire way to burn an exhaust valve.

That's correct, 15-20* BTDC is WAY too much. If you don't have a degree
wheel (pulley), find static TDC (it might not be the notch already
there) and get some chalk. Make chalk marks at 1/8" and 1/4" to the
right of TDC on the pulley (engine not running;). Start and warm the
engine, then time it at one of these two marks, the correct one being
whichever one creates less exhaust heat. HUH! you say? While adjusting
timing to either one of these marks, put your hand in the flow of
exhaust (at the tailpipe) and try to determine which of the two timing
marks makes the exhaust cooler. If you can't tell, or there's no change
in exhaust temperature, use whatever mark makes the engine run smoother.
It's a crude way to time an 009, but if you're not equipped to measure
total advance, it's better err on the side of conservatism.

As one of the other posters pointed out, it may be fine at idle or
freeway speeds on flat ground, but if you're climbing a steep grade
(under load), you could have detonation problems.

If it ain't broke.......well, you know the rest....

I read that some guys without a strobe light time their 009s by
turning it till the engine idles fastest. Is that right? Or is opitimal
not necessary the fastest idle?
I tried all three methods. Static, strobe and by feel (above
method). I think both the static and strobe net me the same result, but
by feel, if I let her run the fastest, I think the timing will be in the
region of 15-20* BTDC. That can't be right, can it?
Also, I realized that at 10* BTDC, the total advance will be about
37*. But the thing is I don't hear any detonation. Is it safe?
BTW, my Bug is a '70 std 1600SP, with 009 and 30/31 solex. Is the
carb too small for it? Can I get a better one without going DP? (Money

Thank you!

pulley.Or a strobe with a built in degree dial.Either way you want to rev
the engine to 3000 rpm. and set the total advance for 34 degrees.The total
amount adviced will vary with whom you ask ,but this realy pends on the
quality of fuel used (Octane rating)
The normal "ballpark" advise ranges from a low 28 to a high 36.You asked
whether 37 could be harmful since you could not detect any "pinging".You
will not get detonations before engine is under load.Try a steep hill and
short shift it (a gear to high) If you hear no knocking now , you are O.K.

NEVER time it like that, you noticed yourself how much excess advance it
gave.
If you are stranded in the mioddle of nowhere, with no strobe light or
static light
(a piece of wire and your interior light bulb!!!)
You can time it first to "fastest idle", then turn back so the idle gets
noticeably lower, say 500rpm. You can drive the car to a mechanic or
maybe home for a REAL tuning.

No it can't, it will destroy the engine.

No, it is NOT safe. You cannot always HEAR detonation. And it doesn't
even occur at all engine loads and rpm, it is worst under heavy load.

That carb should be just fine, but if your engine is otherwise stock, I
would recommend replacing the distributor with a late model new one. The
kind that has both vacuum and mechanical advance. That is the best
distributor for your engine, and it will work SOOOO much better than the
009.
The 009 should only be used if you have dual carbs.

up, it's that I'm not happy with the performance.

I used to be proud for NOT using a .sig file, but I guess I should start

Make sure that your engine is at operating temp when setting the timing.
Often if not always when the engine warms up the motor will want to start
pinging if the timing is set too far advanced.You might not notice the
pinging untill your going up a hill or summer comes and the motor gets nice
and hot.SO keep an ear open and the muffler on till your sure its set right.

run more than this with a vacuum advance/centrifugal combo, but the 009
doesn't qualify.

position at idle. This will cause you to be too far advanced. I like to set all
timing at the distributors full advance setting. This can be accomplished by
warming up the engine and revving the engine to 1800 to 2200 RPM , while at
this RPM set your total advance at 28-30 degrees. If you dont have an advancing
timing light, use a degree pulley or mark your steel pulley at 28-30 degrees
then set at the split in the case.

you will have to go searching for it. When it's in the .sig, it makes life
easier. One less thing to remember.

I believe you are correct.

it, and am so much happier. I didn't believe the whole thing about "Solexes
go hand in hand with the vacuum distributor" but now I am a true convert. By
the way, I would love to sell my "hot-rod special" chrome 009, used
for -1000 miles, to someone who has the time and patience or the dual carbs
to appreciate it. I'll take $30.00 or trade for a 5-lug road wheel, or be
creative! I love to trade!
