Just bought a used DLA 32cc gasser and will bench-run it soon. Found one problem though - the spark plug cap will NOT snap on and stay in place as I want it to. It falls off at the slightest touch. Therefore I fabricated a piano wire spring to secure it in place(see pics) The plug cap metal shield does indeed touch the plug body but I assume that is intended or at least allowed..??!!
Please comment on this before I start up the engine and possibly destroy something in the process..

..! THANK YOU..!
