If the pull start is turning but the crank is not, the chances are, the one way bearing has collapsed. This is the but that grips when you pull the starter, but then free wheels when the engine is running. These are available and are easy to fit.

Yes - when I last used it I can remember I thought the pull start had snapped. But now I can see it hasn’t , I think you are absolutely spot on with your diagnosis there. The pull start just spins easily and the flywheel is absolutely stuck solid. 

Thanks again - looks like a bit strip operation going ahead , I have nothing to lose and might learn a bit along the way!

The other thing that is missing from that picture, is the clutch bell housing. The clutch is there, but you are missing the drive sprocket off of the end. Did you take it off, or is it missing?

Hi yes I just pulled that off

Thank you so much for the tips, I will certainly keep you all posted as I progress :-)

Biggest round thing in pic is "flywheel" and yep it's connected to the crankshaft and that will turnover the engine. Grab it & turn it by hand, it should turn in both directions with pullstart removed.

Pullstart will have a oneway bearing typically, this will gunk up & not engage after a while. If it does engage, it'll prevent you from turning over the engine backwards.

Old used engines gunk up from carbon & dried castor oil. Remove the glowplug and the backplate (often same as pullstarter), take off the carburettor is you can. Then fill the engine with penetrating oil at all 3 holes. Might take days or weeks to free the works; hopefully it's not rust that's seized it up. 

 

A sprung pullstart can be rewound & reassembled with patience. 

 

Thanks! I’ll certainly give that a go. I noticed the throttle lever also seized with the build up of gunked-up spilt fuel, and probably the rest of the engine is the same way. I’m afraid I wasn’t so careful when I was a young lad playing with it and so it has been neglected and then left to disintegrate, such a shame!  

As for the recoil , I’m on my 5th attempt! I’ll get there :-)

I’ve just dug a little deeper.

Should the large toothed wheel here in the picture turn ? Because the pull start is turning freely (not like it is attached to anything) and this large wheel is seized solid. I’m thinking something is seized inside here and this engine is junk. 

Definitely now on the lookout. I have also seen how the engine mounts to the chassis to fit a new engine.

Hi Guys thank you so much for the replies. This is great news! 

So I’ll keep my eyes out for a motor and crack on with the strip and rebuild and keep you updated. 

A few pics attached as you can see it’s seen better days.

Hi All, I am rebuilding my RS200 which hasn’t run for probably over 25 years. I am currently de-gunking all the components. I have no idea whether the motor will run. The pull start was jammed so I undid the glow plug and pulled it and the motor did turn but the pull start didn’t recoil. 

I attempted to remove the pull start but couldn’t so I took off the c clip (the part that the manual says not to remove) and the recoil mechanism flew out. I don’t think it can be rebuilt (at least not by me).

I used to love playing with this machine it was great fun and I want to get it back up and running for the kids. 

So - I don’t mind spending a little bit of cash on it. Do you guys know if any of the currently available 1/10 IC engines might be a straight fit (or easily modifiable) such as the GS11 ? 

Or.. whether you can still buy the pull start mechanism or again whether another pull start would be a straight fit? 

Appreciate your comments and will upload some photos of the rebuild and the engine later on.
