--> RV9-List message posted by: "Bill Repucci" <bill@repucci.com>
I purchased the above mentioned engine for my RV-9. It appears to be in
great shape and has low time, I'll find out more when I start
disassembling it.
The only gottcha is that it doesn't have a fuel pump, which prompted the
following questions:
1) What O-290 accessory cases accept the fuel pump and where should I
look for such a thing?
2) Can I substitute an accessory case from an O-235 or O-320? If so,
which ones?
3) Are any of you flying with an Aero Carb from Sonex
(http://www.aeroconversions.com/carb_index.html)? If so, could you give
me some feedback?
If all else fails, I'm thinking I could install two electric fuel pumps,
with check valves, one pump fused directly to the battery, etc. but I
would prefer to have an engine driven pump.
Thanks for the help!

Hi Bill,
Not positive, but you could do some checking....there are a lot of the older
series narrow deck O-320 parts that fit on the -290's.
The Sonex carb, however I can give you some advice.......Stay away from
it!!!!! There are 2 newer Sonex's in the hangar next to me, and I've seen a
couple more fly in here to see these guys. One of the Sonex's has the
Aerocarb, and one has the regular bing. The Aerocarb has nearly killed the
one owner not twice, but THREE times. He's replaced the throttle slide no
less than three times with significant changes from Sonex. The first slide
was Aluminum, but it was sticky (and got stuck at idle on him in the
pattern) so they replaced it with a Delrin Slide. This worked for awhile,
but then on one flight the idle mixture rod screwed itself shut and the
engine died....So, then next, Sonex went back to an aluminum slide that was
contured, and coated with teflon, but this too gave them problems, so the
guys are back to the Delirin Slide with lot's of locktite on the mixture
rod.
Also, mounting these things is not a bowl of cherries. The cable is
basically held in place through a hole drilled in the carb itself, but if
it's not PERFECTLY straight, the slider sticks, usually in idle posisition.
As an A&P I've helped him MANY hours with this thing, and I've seen him dead
stick it in at least 3 times because of this carb. Meanwhile the guy with
the regular carb has been happily flying!
All that being said, some people are flying with them, and I'm a very
progressive builder/pilot/mechanic, but I'll tell you this. You couldn't
pay me to put one of those things on my plane or car, and I won't even fly
in the plane with that carb on it.
Regarding the lycoming solutions, the old Marvel carbs have over 50 years of
proven reliability, they're reasonable to overhaul, and dirt simple to work
on. The Aerocarb looks simple, but wait until you have to start
adjusting!!! Sometimes, if you get the idle arm on wrong, you can't shut
the thing off without using the key, other times the cable is a nightmare to
get straight. I could go on for hours!!
Cheers,
Stein Bruch
RV6's, Minneapolis.
