jlwoodward Posted March 3, 2021 Share Posted March 3, 2021 Any special technique required for cold starts? For example the C152. I've flown a real one. I don't see any fuel pump switch and the fuel shut off valve appears to be just a picture. The engine will crank but not start. Ctrl-e does work Link to comment Share on other sites More sharing options...
neilends Posted March 3, 2021 Share Posted March 3, 2021 Any special technique required for cold starts? For example the C152. I've flown a real one. I don't see any fuel pump switch and the fuel shut off valve appears to be just a picture. The engine will crank but not start. Ctrl-e does work Following this thread, because I've had similar problems. I am able to start a C-172 by turning the ignition the old fashioned way. But there are other planes where I am apparently missing something, because I turn the ignition, the engine starts, the propellers begin moving, and then it dies. There is a fuel pump switch and shut-off valve in the C-172 and both do work. I don't know about C-152s.

jlwoodward Posted March 3, 2021 Author Share Posted March 3, 2021 I just checked the 172 and could not start it except by ctrl-e. Fuel selector to all, fuel pump on, mixture control moves correctly. Didn't see a fuel primer. Link to comment Share on other sites More sharing options...
hansb57 Posted March 3, 2021 Share Posted March 3, 2021 Push in mixture, shut off valve between seats, master switch and it starts 17-10700K, RTX3060TI, 32 ram, 500G M.2 SSD. Windows10, MSFS on 500 SSD Link to comment Share on other sites More sharing options...
jlwoodward Posted March 3, 2021 Author Share Posted March 3, 2021 Found the fuel shut off valve after much difficulty. The 172 now starts. Still looking on the 152 (I flew a 150 that had the Continental engine). Link to comment Share on other sites More sharing options...
Patinthedesert Posted March 3, 2021 Share Posted March 3, 2021 The way to do this that I have found is to follow the checklists. Pick it from the dropdown menu on the upper screen. The button with the check mark. These walk you thru the start-up procedures for the plane that you are in. If it calls for a switch or control that you can't find, click the Evaluate Item button and it will show you where. Both the basic Cessnas are well documented. Some others seem to be a bit more sketchy. Link to comment Share on other sites More sharing options...
jlwoodward Posted March 4, 2021 Author Share Posted March 4, 2021 I don't see any way to manually turn on the fuel valve in the 152 and the check list didn't do it, but alt-v turns it on and then the engine can be started. Link to comment Share on other sites More sharing options...
hansb57 Posted March 4, 2021 Share Posted March 4, 2021 You have to hoover over te area just behind the valve, closer to the seats.

rjdahlen Posted March 4, 2021 Share Posted March 4, 2021 A real Cessna 152 does not have a fuel pump. Once you turn on the fuel (the valve on the front of the floor between the seats) you use the primer, which is right below the parking brake. Put the cursor over it and click and you will see the valve move out and back in. Generally you prime three times. Make sure your mixture is full rich and the throttle cracked about a quarter and you're ready to start. Link to comment Share on other sites More sharing options...
jlwoodward Posted March 5, 2021 Author Share Posted March 5, 2021 Finally, I found the shut off valve. I think what happened is that I have my display set up for low vision and it seems to move the tool tips around and cut off parts of windows.
