desmogging basically gives you more room under hood, makes it easier to trouble shoot problems and gives you a little more power when done correctly. have jim c. or mark a. rebuild your carb they are the only two who seem to know how to do it. good luck and welcome
Desmogging does not hurt the engine, and can actually improve gas milage, but I doubt you are going to get one of us California companies (especially those of us who have ARB exempted products) to print an instruction sheet on desmogging. That would kinda be like giving the ARB the middle finger salute!!!!
