Fitting a smaller flywheel

[fracture14]

Hi everyone,

I am new so go easy on me. I have an Ansmann Vapor, its my first car, I have the issue that it creeps when its on idle. I have read a few threads on the solutions (clutch shoes, springs, idle screw, tuning etc but still not having a luck.

As a solution I am thinking of changing the clutch and through some research I have seen an adjustable clutch and flywheel kit.

The Flywheel on this is 35mm and my current flywheel is 37mm, so my question to you is what are the issues, if any, if I fit a smaller flywheel?

Thanks for your time.
