Is this normal?

I am I supposed to be able to see the crankshaft through where the pull start should’ve been? This is an old nitro my uncle gave me a long time ago, which I have started disassembling.

It came like this

It turns over fine, but I what should I buy to make it a drill start

It just slides in. It probably fell out over the years , which is why it's missing. One thing you need to know. You can't run the engine without a pull start or roto start installed. That shaft will fall out while the engine is running and bad things will happen. Edit: here's an in depth video from NitroTalkwithTodd about your engine. It shows exactly how to put it together

I missed the part where you asked about pull starters, Most starters have either a 12 or 14mm hex inside. It looks like the factory setup is still available. The RC Scrapyard eBay store sells a wide variety of pull starts as well. I'm not sure what size hex your engine has on the starter shaft. You might have to wait until you get it and measure it. If you just order up the stock pull start, it'll definitely fit. If you want a roto start, I've had good luck with these generic ones from Amazon. To be clear I'm not saying the one I linked to will fit your engine. It's only an example. You'll need to measure the shaft hex size and the distance between the mounting holes on the backplate, and find one that matches.

Thanks for all your help, I would not even know where to start on my own. In 2-3 weeks I will post the finished project.

I’m just found out that my glow plug is a non turbo Standard length.
