Need help with an old jeep 4 banger engine.

I am working on a chrysler 4 cylinder engine that is in a Miller generator/welder. It's around an early 60's model. My dad seems to think it's a Jeep motor.

My problem is I got the firing order all messed up and there is only one spring per cylinder, not two per cylinder like a chevy. So I can't watch the valves to find TDC #1.

Let me know if you are familiar with this type of engine and if you know the firing order, thanks.

Most every 4 cylinder I know of is 1 4 3 2.

That's all I can contribute.

If there are only 4 springs under the valve cover then it is an F head Willy's/Ford engine and the intake valves are in the head and the exhaust valves are in the block. This is half flathead and half conventional like today's engines. Yes, firing order is 1-4-3-2.

You were the guy I was hoping would find my thread, thanks 4x4high.

Looks like an F-Head to me. There are only two commonly used 4 cyl firing orders. 1-4-3-2 and 1-3-4-2
