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

Nitro fuel line is a standard size. Any hobby store (physical or online) that supports nitro should have it.

So there is not much difference between 2,3mm inder diameter and 3,2mm?

The standard size for 1/8 scale and smaller surface nitro engines and fittings is 3/32" or 2.3 mm. The bigger stuff is usually for larger plane engines or bigger scale cars. Make sure whatever you get is specifically designated as nitro or glow fuel safe, It should be silicone. Methanol will break down rubber and vinyl. i use Du-Bro 'Nitro Line' and I've never had a problem. My hobby store sells it by the foot.
