Valve spring

[DanielStang]

Is it possible to run 4v valve spring in a 2v motor without problem. ? ...I think I received the wrong set... not sure if the 4v spring are a little bit shorter ? :dontknow:

Thank you!

I believed the 4v springs are a different size than the 2v spring.

The 4 valve springs are very small compared to the 2 valve. Send them back.
