Hello to all:

Windows 7 Pro, up to date as of Feb 26 2018, FSX Steam Edition Download, and proper operation (FSX Cub) achieved with Hotas Warthog throttle and joystick, T-Rudders & Track IR. Purchased and downloaded A2A Cub and Accu-Sim as a bundle, providing two zip files which I extracted to .exe files and installed both successfully, Airplane installed first, then the Accu-Sim package.

All was well, flew the default in-flight harbor pattern several times, got the joystick and throttle, rudders working successfully, doing some landings etc. Then I decided to assign a Hotas Throttle switch to carb heat (which is necessary in the real airplane) and from then on the engine seems to run very rough and doesn't develop any power. Periodically I get a text message in the upper left hand area of the display which indicates that 'An engine is not started, Hit Ctrl-E to start an engine' or something very similar to that. Ctrl-E does not start the engine though, I have struggled to find out what is going on without success. Same Free-Flight simple mission - beginning in the air etc. I removed the carb heat switch assignment of course but the rough running engine continues anyway. Engine seems to hardly produce any power at all (approx 1500 rpm max) and then dies if I make a successful forced landing. Cannot be restarted with Ctrl-E.

Reboot, etc, same symptom. Default FSX Cub still works properly. I'm actually training in a real J3C65 for a tailwheel endorsement to my PPL and was hoping to get some realistic practice. Any comments or suggestions would be greatly appreciated.

Thanks in advance to everyone,

jda8818

Hello jda8818 and welcome to the A2A forums.

I think the first thing to check in your case is that the "auto-mixture" tick box in the FSX realism settings isn't selected.

Thanks,
Nick

Thanks for your reply, Nick ...

The 'auto-mixture' check box was indeed checked in the realism category, but unchecking it simply causes the engine to die immediately and windmill at about 150 rpm rather than run rough and die on landing. It does have an affect though, which might be a clue.

Interestingly enough, only the first two Cub simulations (normal sized tires, yellow paint scheme and blue/yellow paint scheme) exhibit the rough running phenom - the other versions with large tires, floats, etc seem to run fine (up until this point). So there may be some commonality between the first two choices versus the others. I don't like to practice in the models that are performing properly because the airplane I'm flying resembles the simulations that I'm complaining about (regular sized tires; tire size affects the view from the rear seat). Anyway, I've still got the problem.

As always, any comments or suggestions will certainly be appreciated.

Thanks again for your input, Nick,

A-26:

I guess I need another clue ... I'm not immediately locating the maintenance Hangar. But maybe I've neglected some simple task? Drain the fuel sump? Clean the plugs? Comply with the Marvel-Schebler carburetor AD notes?

Clues, Clues ... I need clues ...

Shift 7 ?? I'll try to motivate myself, get up out of this comfortable chair, and check it out.

Glad to hear, check your windows start menu > A2A Simulations for the manual for your simulation. If ever in doubt though please do as you did and post here on the forums so we and the community can help or point you in the right direction for getting the most out of your fs hobby or using fs as a training aid for real life flying.

thanks,
Lewis
