So I just bought a 4 stroke bicycle engine and had it installed.

It’s reviving up high and my wheel is spinning like I’m hitting the throttle so I tightened it and it quieted down but the wheel still spins

Welcome to the forum, it sounds like you need to lower the idle or the clutch is not releasing.

I lowered the idle but how do you get the clutch to release?

 

[Greg58]

Most clutches have springs that make them release, you may have to take a look inside to see the problem.

I would try rolling the bike back and forth without the engine running, maybe that will make the clutch release.

Does the clutch spin nice & free when the engine is turned off?

If so?, there's nothing wrong with the clutch & you simply need to lower the idle speed a little more.

If the clutch doesn't spin nice & free when the engine is turned off?, then there's something stuck inside the clutch.

It's help to know what kit/engine you had installed.
