I have a play car that I adjusted the valves to what was under the hood and now the thing sounds like a diesel. Can anyone tell me what the correct clearance should be. I believe the intake was .020 and the exhaust was .024 under the hood but that sounded excessive to me.

 

welcome to the forum. .009-.011 ex .007-.009 in. Also it should be printed on your door post data plate. do it cold. Might want to get a service manual for great information.

 

This is just a play car. I really didn't think about it but it may have been in mm instead of in. I will have to check to see.
