The rocker cover bolts should either be a slot screw or will use a 2ba screw that undoes with a 1/16th allen key. Again if these screws are damaged there are no replacements but an M2 screw will fit in its place without modification. The carb and exhaust screws will be M3 and will work with either a 3/32 allen key (slightly sloppy fit) or 2.5mm.
All of these issues with mixed threads have now gone as all screws are metric and easy to obtain
There are ways to get the existing screws out of your engine if needed but the best advice I can give is not to take it apart at all. If its working well then it is best left alone!
I have no plans to take anything out. I am banking on reliability and longevity of Laser engines. However, if something happens that I caused and they need too, I think they will be coming across the pond unless it can't anymore because of it's age. The engine has only been bench run and well oiled. Everything looks new and feels good. Thing is I never asked how old it was before I bought it. I am planning on putting it in a Ziroli Ercoupe. Should fit in there just nice. Picture is not my Ercoupe just a shot to give you an idea.
Again thanks for all the info and your time.
