Iv'e bought a new os 21 engine and then i started to do the 1st tank break in when the engine starts to warm up the wheels starts to spin rather fast to the point i have to stop the engine the idle gap is very small. My thoughts would this be down to the lsn being lean making the wheels spin at idle. Thank you.

After you reset your needles ( if you need to)....

Stiffen up the clutch springs so they wont make contact with the bell. Your clutch is engaging at too low of an RPM.

I would say richen the LSN to where it is flush to the housing and then check your clutch. Check the springs the shoes and the bearings. When bearings go bad they will not allow the engine spin without the clutch engaging.

It's also possible your clutch is stuck on the clutch bell, if one of the clutch spring broke or loose.

I have a feeling the "OS" engine you have isn't the OS engine we think it is:

LOLz, awesome find. This Hotrob1 does not know how to tune, clueless he is.

HR1, there are plenty, and I mean gazillion videos on Youtube. Seems to me you are doing things because other people do them, but you have no idea how each part on nitro engines, clutches work.
