Cannot start the CAP-4 Paulistinha

I just cannot start the CAP-4 engine (MS 2024) from a parking position. I did the external check, followed all the checklist steps, battery on, mixture on, carb heat cold, mags on, fuel selector both, two throttle pumps, clicked on the note on the panel to crank the prop, the engine starts and runs for a sec, then it dies. I tried it several times, same result.

If I start on the runway, I can start the engine normally (after shutting it down, because if I start the flight on the runway the engine is running by default)

any ideas on what i’m doing wrong? thanks in advance.

Having never done it before, I tried following the EFB checklist like you did. No start!

It seems they have left out an important part - priming 3 times with the primer on the far left of the instrument panel. (left of the ignition switch).
Also, the “open” position for the fuel cutoff valve is pressed down. If you pull it up (open), after a while the engine will fuel starve and quit.

On other aircraft I have also found that cranking the engine while slowly moving the mixture from lean to rich works quite well.

I got 3 successful starts in parking following the above.

Hi Talles, thans for the response!

There’s no priming switch or fuel cutoff valve for me.

Right you are. Sorry - I was looking at the wrong bird.

Oh, thanks anyway. Happy flights, sir!

I put tanks to both, pumped the mixture a few times, set carb to 31%, clicked on the spin prop ticket and hey presto, up she started

Thank you! I will try that!

If you go to Settings > Camera> Zoom, you can change that. I have mine at 65 Zoom and it’s way better.

That’s besides the battery and mags which on the bravo is easy.

I hope it has worked for you

Let me know if find a way to start the aircraft. I also can’t start it

I just tried the check list again, this time on the CAP 4 and she started right up on first try - no problems. I followed the recommendation I mentioned before with the mixture in full lean/cutoff before I started to crank, gradually moving it to full rich when the engine caught.

As others seem to be reporting the same problem, it might help to know that I am running the PC Store version of the sim with SU3 installed.

I’m on Xbox, SU4. I’m following all the checklists, it doesn’t start no matter what xD

It starts, the yellow note disappears and shortly after it appears again, and RPM drops to zero, then engine shuts down.

Here are some screen captures of my settings:



that worked for me.

Well I am on PC, steam. I turned on battery, alt/mags, fuel on both, pumped the mixture a few times, carb heat to 30% and cranked the yellow ticket. Throttle was just cracked open, RPMs at about 900. She just started and kept on going. I did NOT use the primer.

That sounds electrical to me. Make sure you have the battery switch in the correct position. I don’t think the switch settings are all that intuitive, so please take a look at my screen captures in my previous post.

I meant to include this setting, too:

I have everything set up correctly, it’s a very simple aircraft, no much room to do something wrong. The checklist says to put the Fuel Selector down, the aircraft spawns only with fuel on the low tank. I’ve tried all tanks. It doesn’t work. I’m going to upload a video showing it.

Magnetos: ON
Battery: ON
Throttle: Cracked
Mixture: Rich
Carburetor Heat: Cold

Everything is in the correct position xD

Yeah, it’s beginning to look like an XBox version issue. I don’t doubt you. No need for a video. Sorry, I can’t help.

BTW, thanks for your query. I just flew a short circuit around my airport and forgot just how nicely it behaves and how much I love it!

Try putting in some carb heat. Fuel to both tanks. This worked for me.

If none of this works I agree with Tallest Parsley - it must be an xbox issue. It is just about the simplest plane I have flown in the sim. There is no other hidden process.

I’ve tried that already xD All combinations of Mixture and Carburetor and Heat, with every tank, full of Fuel. It’s most probably a bug.

It’s not Black Square or A2A simulation going on
