Ihttps://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=2232910754 The engine was way to small for such a big truck. I replaced the small engine by a medium one to start the bus you only have to press the old engine button but keep it pressed so the engine system can restart it and boost the engine till it reaches enough rps to drive. I messed up the fuel tank size ,the gear box and may be some other system. sorry for that but i needed space to work. I hope this helps you out tell me if you want me to delete my workshop page because it is your creation.

i'll try to help :)
