"Hello community! 🌟

I'm facing issues with my 1989 Winnebago Chieftain – it attempts to turn over but won't start. I suspect it might be the spark plug or air filter. Could someone guide me on where to find these components?

If possible, please refer to the attached pictures for better insight. Your expertise is highly appreciated!

Thank you all for being an amazing community, and I'm grateful for any help provided. 🙏"

You mean how to get to the engine?

If so, that would most likely be under the cover between the two front seats.  That is how we access the engine on our 86 Minnie Winnie.
