I've got to give this a try ...

It's a tough call on the assignments. The RV-3B is pretty certain but the Valkyrie has been around a while and Mikey has had numerous upgrades.

I went with 2 Pmags and a carb for my RV-3B. I chose the Pmags for ease of starting and efficient fuel burn.

My engine was delivered with a carb, and since I'm not planning on acro and don't plan to do inverted flight, that let me eliminate the inverted system and the fuel tank flop tube. On my certified plane, I've got an ARP carb ice detector and it finds ice in real time, so carb ice is not an issue. It's easily identified and controlled, and I have one for the RV-3B. Spruce sells them if that's a concern for you.

At my location, much of my flying is full throttle and leave it there until I descend for landing. Carbs aren't that bad at full throttle, I've read.

There you have it.

Dave

Close - you've got the six and eight reversed. Mikey is totally old school!

There's been a surge in polling data (161 results) from fuel injection 5:2 over carburetor. The carburetor install with single EI are 4:3 while the fuel injection installs are back up to 2:1 in favor of dual EI.

The poll has settled down (for the most part). I'd like to say "thanks" to everyone for participating and for the comments.

As of now, with 170 data points, it's 5:2 with fuel injection results more than double that of carburetor. The carburetor results are 6:5 with the single EI reporting ahead. The fuel injection results continue to hold at 2:1 in favor of dual EI.

I have replaced mags on my 0-290 with dual ignition (EFII). Injection to come later. Looks like FLYEFII has some new stuff out.
