| Subject: | Fuel Flow Setting |
Lee,
You are right in following John Deakin's advise.
I have a carb on my 0-360 A1A.......
I have installed the enrichment kit
AND drilled the jet larger.......it really brought the temps down.
The FF on TO is more connected to the induction system than HP....I think.
The published numbers in the POH's are very misleading as they are done for
OEM installs.
Each setup should be tweaked, but I don't see many people talking about it.
Good Luck
Bob Martin

Bob,
I would like to learn more about the enrichment kit you refer to. I have
an O-360 A1A, carburetor, high compression pistons and LASAR ign. with
C/S prop.

| Subject: | Fuel Flow Setting-enrichment kit |
Dale,This is what I have learned:The enrichment kit is sold to convert the
M4-5 10-3878 carb to act more like it's richer brother M4-5 10-4164The kits
part number is 666-660.........I know...kinda weird number huh?it costs ab
out 250.00 list is 292.91 sell for 234.32 plus freight....Precision Air
motive produces the kit, and has been since 1962 to fix a problem on Mooney
s I was told.You can't buy direct from Precision so you have to go thru a d
ealer.I used Penn Yan Aero iin NY 800-727-7230 315-536-2333The tech at
PennYan Aero offered to install the kit for me for about 100.00Labor plus
freight obviously. I figured, in for a penny, in for a pound, so I might as
well learn from this one too.Any good A&P should easily be able to follow
directions and install the kit.There is more work involved in removing the
carb and reinstalling it than the actual work installing the kit, but it do
es involve removing the float and reinstalling it.Interesting note...the ma
in jet nozzel in the new kit was not measurably larger.it did have a bushin
g that reduced the amount of air thru one of the carb body passages.So I'm
assuming (we know what that means) the enrichment is acheived by reducing a
irflow rather than just putting in a larger main jet, which is what you wou
ld expect.The original main jet and the jet in the enrichment kit were diff
erent part numbers although I couldn't see a difference. The fuel flow did
change however, because my temps lowered. If you have cooling problems or
think you have, read John Deakins articles on AVWeb.http://www.avweb.com/ne
ws/pelican/182176-1.htmlThis is assuming (here we go again) that you have c
hecked obvious things like baffeling etc, already! Now, what carb do you ha
ve installed? if it is the 10-3878 then you will need the kit.if you have
the richer carb 10-4164 then you are already better off but probably need m
ore fuel at TO. I did this by drilling the main jet out. Yes, you have to
take the carb off again, if you took it off to install the kit. Here is a
link to an article on VAF by Jon Foy:http://www.vansairforce.net/articles/h
ighcylinderheadtemps.htmHe had Lasar ignition too, and he seemed to blame h
is temps on the ignition system.He doesn't give a lot if detailed info so I
can't comment on his install.I have 2 slick mags for the record. The kit..
...for the record is just a small bag of parts.a main jet.an idle jet.a bus
hing.a drill bit to help install the bushing if you have an older carb.a ne
w bowl gasket.a new ltab locking washer for under the main jet.a small fibe
r O ring to go under the tip of the main jet.a decal and 2 pages of very va
gue instructions for 1962 (I guess people were smarter then)Thats it!It doe
s not include new tab lock washers for under the bowl screws.It does not in
clude a new carb to induction system gasket. Is this the info you were look
ing for ?I can go into more detail if you wish.
You will enjoy John Dekin's articles.Happy to help.Regards,Bob Martin

Thanks Bob. I have a copy of Deakin's article in my engine file. I'll
read it again. I don't think I have a over heating problem but want to
stay up with this issue.
