Basically I've been bequeathed a nitro RC car from my Dad who I dont think has run it in many years and bought it from someone else assembled years before that. I've had a Traxxas Stampede notro version but that was 15 years ago so I'm well out of the loop on repairs.
My plan was to get some fresh fuel and see if it runs but I've spotted a bit of an issue in that it's had a replacement engine swap at some point (I know this as it came with the old one) but the output shaft appears to be missing a bearing and circlip? And I have no idea where to start looking for a spare.....

Thanks, that's really helpful. I has a suspicion that it's been run like this in it's current bodged state and the force of the drive shaft cog just pushes into the drive cog but it will end up just stripping it.
Now I know its a pinion, a quick Google and a vernier caliper and I can figure something out I think!
Something like this?

Does the grub screw tighten the pinion using the output shafts groove?

Behind that clutch assembly there is a flywheel type part which appears to be the braking system that the throttle servo presses some sort of brake lever onto it.
That has some pins on the pins on the back that aligns onto the output shaft hub. There's no keyway that I can see anywhere on the length.
I think the best option as you say is to try and find a replacement clutch and pinion assembly. How do I find the engine model, is it underneath where it mounts to the chassis?
