Hey guys I apologize if this is on here but what is the engine model of a 78 gt 18 onan and is there a manual for the engine on here. I'm going to pick it up tomorrow I'd like to read about the engine and carb.

It's a B48M, GA018 I think. We have several Manuals here for that Onan.

There should be a fairly large plate on the flywheel shroud of the Onan with the model number and other info. Here is mine and you can see where it identifies it as B48M. 5A2E46AF-9BE3-4C3C-879F-96AEE76F1E3B_zps
