| Subject: | Re: Dual Bing Carbs Hookup |
Hi Trey,
I put the linkage arms to the inside between the bings and made a
linkage that connects both carbs at the linkage.
see link and note the solid tubes connected by a bent flex link, seen
between oil filler and alternator.
http://www.macsmachine.com/images/controllinkages/full/abingcarbscable.gif
The firewall linkage shown is the way I connected a A-820 friction
throttle with wire p/n 05-09436 control to my firewall mounted arms
each side and it allows the cable to push further without serious
bending of the larger throttle wire.
The collet fastener you see holding onto the throttle wire is called a
.078 wire grip and it allows you to
shorten the throttle wire and sheath p/n and attach the wire to the
linkage. p/n 05-16001 at aircraft spruce.

Then see the .065 music wire connection between the firewall mounted arm
and the carburetor. It uses the sheath as a guide
http://www.macsmachine.com/images/controllinkages/full/throttlewire.gif
The pieces I made look like these two assemblies. Connecting link
between carbs and wire connection. See link.

The following link is my enrichment connection and it retains two cables
as before. Some call it a choke, but it pulls both cables.

This is really simple and works really well without any springs for the
throttle arms to get in the way. Works like any Cessna throttle.
Hope this helps a bit,
Larry McFarland

Gary,
It would seem that you need to put the exact amount of oil that would
read full in any case and re-size the dipstick length to capture the
full mark with the tail down.
If it's a Stratus EA81, that should be 4 quarts with the short filter.

the new dipstick is a generic replacement - it is very long. it bottoms
out on the bottom in the oil pan without showing any oil when there is
sufficient oil. I don't know exactly where the dipstick ends up
relative to the oil pan or oil level - maybe I need to pull the oil pan
and see - but I'm guessing that I need to figure out a different way to
check the oil level or maybe get one of RAM's oversized oil pans.
