There are 3 main ones. Grt Dynon (as well as it's subsidiary AFS) and
Garmin. Depends on your budget and mission.

Most carbureted Lycomings have a mechanical diaphragm pump, which is
non-adjustable. With an old mechanical fuel pressure gauge you would
never have noticed the blip in pressure, and it is not sig ...

Sebastian,
The original battery that Vans recommends is a Concorde RG-25AXC, which
weighs about 24 lbs. I have the Odyssey equivalent, a PC925 at about the
same weight. I have an MT 3 bladed prop ...

Right. I would expect they probably flow matched the cylinders as well.
I would inspect and clean the #2 injector, then swap it with the #4
injector. That will tell you whether it is the injector ...

I found it useful to swap my richest injectors with the leanest first.
After doing that a couple times, I found my #3&4 were consistently the
richest. So I ordered 2 restrictors from Airflow t ...

It will depend on what part of the country you are in. Given the
climate, all summer fuel in AZ is required to be 7.0 RVP for emissions,
which happens to be the same as avgas. Most areas have summ ...

The stock 200 hp angle valve engine is 8.7 to 1 compression and yes, it
is a 100LL engine, no mogas is good enough. The 200hp engine originally
had 25 BTDC timing (and some still have it) but the ...

Just so those that run 8.5 compression 4 cylinder Lycomings understand,
the IO-540 is just a 180 hp O/IO-360 with 2 more cylinders. Same
cylinders, same compression, same stroke, same parallel val ...

93 pump octane mogas should be okay in the IO540 if no alcohol, but it
really isn't the same as 91/96 avgas the engine was certified with about
60 years ago. The Swift fuels 94UL avgas should be j ...

You don't need 3 trim servos. The pitch trim is all you need. You may
want aileron, but really neither rudder nor aileron is needed with an
autopilot. Once you get rudder fixed trim to fly straigh ...

Agreed, however, in most cases it is to deal with two electrically
dependent ignition systems, and/or an essential bus for avionics. I
don't believe the case of electrically dependent fuel system ...

There is no question that mechanical fuel injection has been extremely
reliable on aircraft engines. They have been employed since the early
1960s. The Bendix variety generally goes to TBO with th ...

I agree with the electronic ignition. There are definite advantages.
However, there are trade-offs. AFAIK, only P Mag offers electronic
ignition that isn't dependent on ship's power.

I think the real analysis is that you need two separate power sources
for the fuel injection and the ignition. Using a single battery does not
accomplish that, no matter how you wire it. I believe ...
