Engine not idle

[fstnd]

When the engine does not have a clutchbell (completely no load), it does not want to return to idle. It has the RPM like I apply 40% throttle. I have to block the intake with my finger for 3 seconds just for it to return to idle. The engine sounds very well tuned. Will this be different when the engine is under load?

Yes. That clutch bell is also a flywheel.

Yes. That clutch bell is also a flywheel.

Two different things. The clutchbell being removed shouldn't affect. But not having a flywheel will.

Maybe lsn is lean

That's right: clutchbell doesn't rotate at idle so it doesn't bring any inertia with it

Well the pads inside it would act just like a flywheel.

I just found out a reason maybe why it's like this:

The engine has hardly compression. Why I conclude?
-I can start the engine with pullstart without holding the car
-it's a PITA to start the engine.
-When it does start, it acts OK, but hardly any power
-sounds very well-tuned while having all these symptons
-stalls easily at low RPM

Luckily I own 11 nitro engines and 6 nitro powered RCs so I'm fine kinda sad tho, it's a thundertiger .12

Well the pads inside it would act just like a flywheel.

Oh the clutch shoes, that's right

They would add mass to the flywheel.
